Give Your Children a Floor, Not a Throne: A Better Way to Think About Generational Wealth

From my Engineer Investor account (@egr_investor) on X.

Disclosure: I write both Summitward and the Engineer Investor account.

Say the words “generational wealth” in a personal finance conversation and watch what happens. Nobody asks what it is for. It gets treated as a scoreboard, where a bigger number is a better parent, and the only failure mode is dying with too little.

I plan to leave my son something. Making him rich is not the objective. I would rather he be healthy, capable, curious, and useful to people around him, with a real safety net underneath and no illusion that the net is an achievement. That is easy to say and genuinely hard to execute, because the thing standing between those two outcomes is not a dollar amount. It is what the money is for, when it shows up, and what it quietly replaces.

The clip that plays in my head

Shaquille O’Neal on Earn Your Leisure #141, July 6, 2021. Clip via ESPN, May 16, 2024.

“We ain’t rich. I’m rich.” It is a good line because it is funny and because it sounds like a hard-nosed answer to a real question. It gets shared as though it settles something.

The full answer is more interesting than the cut. On Earn Your Leisure in July 2021, the sentence continues: “you got to have bachelor’s or masters and then if you want me to invest in one of your companies, you would have to present it to me and I’ll let you know.” Elsewhere in the same episode: “There’s one rule: education.” By 2023 he had a name for the arrangement, “respectable nepotism,” and a summary of it: go to law school and graduate, and you get a big bag.¹

Fund the education, require a pitch before funding a business, decline to underwrite a lifestyle. That is a capability floor plus a conditional opportunity fund. It is a considered allocation of generational wealth, and the viral cut removes every part of it except the punchline.

Worth being precise about one more thing, because the headlines are not. Shaq has never said anything on the record about his will, his trust, or his estate plan. Every “Shaq won’t leave his kids a dime” framing is an aggregator’s invention. What he actually described is a lifetime transfer policy, and refusing to hand cash to a healthy adult is a different decision from leaving them nothing when you die. People conflate the two constantly, in both directions.

The allocation is the whole game. The public conversation about generational wealth almost never reaches it, because it is stuck arguing about size.

Most of the transfer happens before the will is read

An inheritance received at 55 is the last and most visible transfer in a long sequence. By then a wealthy parent has typically already provided stable housing, a school district, tutoring, health care, college funding, a network of adults with useful jobs, a cushion during a layoff or a failed venture, and a running commentary on money that the child absorbed without noticing.

Separating that environment from genetics is hard, which is why the Swedish adoption data matters. Black, Devereux, Lundborg and Majlesi matched adoptees to both their biological and adoptive parents and tracked wealth outcomes. Adoptive-parent wealth predicted adoptee wealth before any inheritance changed hands, with what the authors describe as a substantial role for environment and a much smaller role for pre-birth factors. When bequests were included, the adoptive-parent relationship became considerably stronger.²

The detail I find most useful for parenting: the authors report that environment matters relatively more for wealth-related behavior, meaning savings and investment decisions, than it does for human capital. How your child handles money looks more learnable than how they perform in school. That is an argument for teaching it deliberately rather than hoping it transmits.

Two things follow. A parent who leaves nothing may still have transferred an enormous amount of generational wealth. And a middle-income parent who covers tuition, or lets a 24-year-old move home rent-free for a year, is transferring generational wealth too, without anything resembling a dynasty.

What inherited money does to work

Economic theory makes a plain prediction. Give someone money they did not work for and they can afford more leisure. The interesting question is how much.

Lotteries answer it more cleanly than inheritances do, because the winners are close to randomly selected. Cesarini, Lindqvist, Notowidigdo and Östling studied Swedish lottery players and found that winning modestly reduces earnings, immediately and persistently, with similar responses across age, education and sex. Their calibrated model implies lifetime marginal propensities to earn out of unearned income ranging from -0.17 at age 20 to -0.04 at age 60.³ A 20-year-old who receives an unexpected dollar gives up roughly 17 cents of lifetime earnings. A 60-year-old gives up about four.

Inheritances land later in life, and the clearest effect shows up at the retirement margin. Brown, Coile and Weisbenner found that receiving an inheritance raised the probability of retiring earlier than expected by 4.4 percentage points over an eight-year window, roughly 12% above the baseline rate, with a larger effect for inheritances the recipient had not anticipated.⁴ The same paper contains a number worth keeping next to every “great wealth transfer” headline: about one in five older households received an inheritance over eight years, and the median was roughly $30,000.

The older result people reach for is the Carnegie conjecture paper. Holtz-Eakin, Joulfaian and Rosen found that a single person receiving an inheritance of about $150,000 was roughly four times more likely to leave the labor force than someone receiving under $25,000.⁵ Those are early-1990s dollars, so scale them before you react to them. And note the outcome variable: labor force participation. The study measured hours worked. Character was never in the data.

That distinction gets lost constantly. Four different claims travel together in this debate and only the first has clean identification behind it:

Someone who leaves a job they hate to teach, to care for a parent, to raise children, or to start something risky shows up in the data as working less. Whether that is decay or the entire point of financial independence is not a question the earnings data can answer. It is worth being honest that the value I place on my own optionality is the same value I would be denying my son if I treated any reduction in his paid hours as a failure.

The evidence on ruined heirs is thinner than the folklore

There is no study in which researchers randomly assigned trust funds to children and followed their character for forty years. The trust-fund baby is built almost entirely from memoirs, family-office anecdote, clinical caseloads, and a handful of famous disasters. Those sources describe real families. They cannot tell you how common the pattern is, and they cannot separate the money from everything else that travels with it.

The closest thing to a clean test exists, and it points the other way. Cesarini, Lindqvist, Östling and Wallace linked Swedish lottery wins to administrative records on the winners’ children. Random wealth arriving in a household produced essentially no effect on children’s scholastic performance or on their cognitive and noncognitive skills. It modestly raised health care utilization and may have reduced obesity risk.⁶

Read that carefully, because it is a narrow finding doing important work. Lottery wins are windfalls to a household, not a bequest structure combined with two decades of knowing one is coming. It is entirely possible that anticipated family wealth affects a child differently than a surprise does. But the popular claim is that money itself corrodes children, and when someone finally randomized the money, the corrosion did not appear.

The research most often cited for the opposite view is Suniya Luthar’s work on affluent adolescents, which documents elevated rates of anxiety, depression and substance use in high-income suburban samples.⁷ It is worth taking seriously and worth reading precisely. The mechanisms Luthar identifies are achievement pressure, physical and emotional distance from parents, and a low sense that anyone will intervene over substance use. Those are features of a parenting environment that happens to be well funded. None of them is a bequest, and all of them are available to a family that leaves its children nothing.

The honest summary is that the spoiled-heir hypothesis is economically plausible and empirically underpowered. If you are going to build an estate plan around a fear, it is worth knowing that the fear currently rests on stories.

What money does for well-being

The mirror-image claim, that wealth cannot make anyone happier, does not survive contact with the data either. Lindqvist, Östling and Cesarini surveyed Swedish lottery winners five to twenty-two years after they won. Large-prize winners showed sustained increases in overall life satisfaction that persisted for more than a decade with no sign of fading, and financial life satisfaction was an important mediator.⁸ Hedonic adaptation did not erase it.

The same paper contains the qualifier that popular summaries drop. The estimated effects on happiness and mental health were significantly smaller than the effects on life satisfaction. Wealth durably changed how people evaluated their lives, especially the financial part of them, more than it changed their moment-to-moment emotional state.

That maps onto what money is good at. It buys safety, flexibility, medical access, and the ability to leave a bad situation. It reduces a specific and grinding category of suffering. It does not generate close relationships, mastery, community, self-respect, or a reason to get up. An inheritance widens a child’s choice set. Nothing in the instrument produces the capacity to choose well, and that capacity is the part that has to be built before the money arrives.

Timing changes what a dollar buys

A dollar is not a fixed quantity of help. Its value depends entirely on when it lands relative to the constraints your child is facing.

By the time a typical inheritance arrives, the recipient’s education is finished, their career is established, their own children may be grown, and they likely own a home. The years when capital was scarce and returns to capital were highest have passed. That is a genuine mismatch, and it argues for moving some transfers forward.

The obvious counterweight is that you cannot give away money you will need. Long-term care, longevity, a surviving spouse, and a medical shock all have first claim. Making yourself financially dependent on your adult child is not a pro-responsibility strategy. A bequest works better as a residual, meaning what is left after you have lived securely and generously, than as a fixed obligation that quietly forces you to underspend for thirty years.

Four layers: floor, catastrophe, opportunity, residual

There is no universal safe number. The same $1 million means different things depending on your child’s age, health, city, career, family size, existing assets and judgment. Setting an arbitrary ceiling (“no child should get more than $500,000”) substitutes a round number for a decision.

Defining the purpose of each layer holds up better:

Underneath the layers is a distinction I find more useful than the dollar figure. Some transfers build capacity and some maintain a lifestyle, and the same amount of money can be either one depending on what it is attached to.

A $40,000 transfer that finishes a degree and a $40,000 transfer that covers three years of overspending are the same line item and completely different interventions.

Where inheritance plans go wrong

Rescuing the same problem repeatedly

A one-time bailout after a genuine shock is insurance. The fourth bailout after the same predictable pattern is a subsidy for the pattern. The test is whether the transfer resolves a situation or funds its continuation.

Manufacturing hardship on purpose

Some struggle builds competence. Some struggle just produces debt, stress, worse health, and a narrower set of options for a decade. Disinheriting a responsible child to make them tougher assumes the second kind reliably converts into the first, and there is no evidence that it does. Remove the obstacles that are expensive without being instructive. Leave the ones that teach.

Incentive trusts that try to run a life from beyond the grave

Conditional structures are where good intentions produce the most collateral damage. Terms that pay only on marriage, forbid lawful careers, require particular religious or lifestyle choices, or condition distributions on having children tend to generate resentment, litigation, and creative gaming rather than the behavior they targeted.

The earned-income match deserves specific attention because it sounds so reasonable. Matching a beneficiary’s W-2 income dollar for dollar pays an investment banker several times what it pays a public defender, and pays a disabled beneficiary, a graduate student, a full-time caregiver or a stay-at-home parent close to nothing. It encodes market compensation as a measure of merit, which is not a claim most parents would make out loud.

Protective terms are a different instrument. Trusts do useful work for minor beneficiaries, disability and special needs, active addiction, creditor and divorce exposure, financial exploitation, incapacity, and concentrated family-business assets that should not be liquidated in a hurry. The line worth holding is protection rather than posthumous management.

Age-gating as if age were the variable

Handing an unrestricted eight-figure portfolio to an 18-year-old is rarely necessary, and staged access reduces the obvious impulse-control risk. But “one third at 25, one third at 30, the rest at 35” is a convention, not a finding. Some 25-year-olds are ready. Some 50-year-olds are not.

For unusually large estates, a discretionary trust with a competent independent trustee handles the variance better than a birthday schedule, provided the distribution standards are legible, the beneficiary is treated as an adult, fees are proportionate, and there is a path toward greater control over time. For ordinary affluent households the complexity usually costs more than it returns. A clean will, correct beneficiary designations, and twenty years of deliberate parenting will outperform a dynasty structure.

Tell them enough to prepare them

Total secrecy has a failure mode people underrate. A child cannot learn to manage assets they do not know exist, and an unprepared heir meets a large portfolio for the first time while grieving, which is the worst possible moment to develop judgment.

Disclosure works better as a ladder than as a switch:

• Young child. Money is finite, our family is fortunate, and what you own is not what you are worth.
• Teenager. How a household budget works, what investing and taxes are, what the family gives away, and the tradeoffs behind real spending decisions.
• Young adult. The broad shape of the family’s finances, your intentions, and specifically what support they should and should not plan around.
• Mature adult. Account structure, advisers, documents, tax posture, trust terms, and whatever responsibilities come with them.

You do not owe a fifteen-year-old a net worth statement. But “we expect to help with education, and you should plan to support yourself” is a sentence a teenager can act on, and it beats both pretending to be broke and implying that the portfolio is their future budget.

The mechanics that actually move the outcome

Federal transfer taxes start at $15 million per person

For 2026 the federal basic exclusion is $15,000,000 per individual, or $30,000,000 for a married couple using portability, under Internal Revenue Code section 2010(c)(3) as amended by Public Law 119-21. The scheduled 2026 sunset was repealed, and the amount is indexed for inflation for years after 2026 using 2025 as the base year. The top federal rate stays at 40%.⁹

The annual gift exclusion is $19,000 per recipient for 2026, unchanged from 2025, or $38,000 for a married couple splitting gifts. The exclusion for gifts to a noncitizen spouse is $194,000.¹⁰ Exceeding $19,000 triggers a Form 709 filing and draws against the $15,000,000 lifetime amount rather than producing a tax bill, which for the overwhelming majority of families makes it a paperwork event.

State thresholds bind far sooner, and they move

Washington is a useful worked example because it shows both points at once. Its estate tax applies well below the federal line, and the rules changed twice in twelve months.

Engrossed Substitute Senate Bill 6347, signed March 24, 2026 and effective July 1, 2026, rolled the rate schedule back to 10% through 20% and reset the exclusion to a flat $3,000,000. The Department of Revenue notes that the exclusion is not set to increase going forward, because the statute’s indexing provision references a CPI series that no longer exists.¹¹ Washington’s brief run as the highest estate tax rate in the country lasted almost exactly one year.

Two Washington-specific details that catch people: the state has no gift tax and no inheritance tax, and it has no portability between spouses, so a couple that wants to use both $3,000,000 exclusions has to plan for it rather than assume it. Twelve states and the District of Columbia levy an estate tax and several others levy an inheritance tax on the recipient. Check your own state, and check it again after each legislative session.

Basis is where lifetime gifting quietly loses

The most common planning error I see is treating lifetime gifts as automatically more tax-efficient than a bequest. Basis usually decides it, and it frequently points the other way.

Property acquired from a decedent takes a basis equal to fair market value at the date of death under section 1014, so unrealized appreciation over the decedent’s lifetime is never taxed as gain. Property transferred by lifetime gift takes the donor’s basis under section 1015, carrying the entire embedded gain to the recipient.¹² For a long-held position with a low basis, waiting can be worth more than the estate tax it exposes, particularly for a family well under the federal exclusion.

The exception matters as much as the rule: there is no step-up for income in respect of a decedent. Traditional IRAs, 401(k)s, annuities and unpaid deferred compensation carry their full income tax burden to the beneficiary. Which leads directly to the next point.

Retirement accounts are the harshest asset to inherit

The final required minimum distribution regulations, T.D. 10001, apply to distribution calendar years beginning on or after January 1, 2025, so 2026 is the second year of full enforcement.¹³ For an adult child inheriting a traditional retirement account:

• The account must be emptied by December 31 of the tenth year following the year of death. The clock was never extended, despite several years of penalty relief while the rules were unsettled.
• If the owner died on or after their required beginning date, annual distributions are required in years one through nine based on the beneficiary’s single life expectancy, plus full depletion in year ten.
• If the owner died before their required beginning date, no annual distributions are required in years one through nine. Only the year-ten deadline applies.
• Inherited Roth IRAs have no annual distribution requirement, since the owner is always treated as having died before the required beginning date. The ten-year deadline still applies.
• Missing a required distribution triggers a 25% excise tax on the shortfall, reduced to 10% if corrected in time. The relief notices covering 2021 through 2024 do not extend to 2026.

The practical consequence is that a large traditional IRA left to a 40-year-old in their peak earning decade can be one of the worst assets to inherit, since it forces taxable income into their highest bracket years. Eligible designated beneficiaries, including a surviving spouse, a minor child of the owner until 21, a disabled or chronically ill beneficiary, and anyone not more than ten years younger, remain exempt from the ten-year rule.

The unglamorous things that decide more than the trust does

• Beneficiary designations override your will. A retirement account or life insurance policy pays whoever is named on the form, regardless of what the will says. An ex-spouse left on a 401(k) beneficiary line has defeated more estate plans than any tax rule.
• A 529 is the cleanest capability-floor vehicle for most families, and beneficiaries can be changed and balances rolled to a Roth IRA within limits if plans shift.
• Review after each life event. Births, deaths, marriages, divorces, a move across state lines, a large liquidity event, or a tax law change. The Washington table above is what a “set it and forget it” estate plan looks like when the legislature disagrees.
• Consider a charitable component if your assets materially exceed what would improve your heirs’ lives. It is a concrete way to express that the wealth carries obligations past the family, and it does so without turning your child’s inheritance into a performance review.

Objections worth answering

“My child should struggle the way I did”

Preserve productive challenge and drop the rest. The struggles that built you were probably specific ones involving effort, tradeoffs and recoverable failure. Reproducing avoidable medical debt or an interrupted education is not the same category, and the evidence that it forges character is nonexistent.

“Leaving money proves I succeeded”

It proves assets remained. A parent who spent more on time at home, education, caregiving or charity may leave a smaller estate having transferred considerably more. The terminal balance is a residual, not a score.

“An inheritance destroys ambition”

It reduces the financial necessity of work by a measurable and fairly modest amount. Whether that shows up as decline depends on whether the person’s motivation was ever anything but financial necessity. A child with competence, obligations, curiosity and relationships tends to stay busy when employment becomes optional. Building those is the parenting job the estate plan cannot do.

“I earned it, so my children deserve it”

They are legitimate objects of your generosity and they did not earn your money. Both are true, and teaching the second explicitly is one of the more valuable things you can hand a child. Gratitude and entitlement are different postures toward the same inheritance.

“I will give it all away so they stand on their own”

Sometimes this is the right call. It is not automatically the noble one. Giving everything away while a child faces a disability, a medical catastrophe or avoidable educational debt prioritizes a story you are telling about yourself over their actual circumstances. Leave room for the facts to change.

Does inheritance drive wealth inequality?

Worth addressing because it is the strongest argument for capping what you pass on, and because the research genuinely disagrees.

Nekoei and Seim found that Swedish inheritances initially reduce relative wealth inequality, since a bequest is enormous compared to a less wealthy heir’s prior assets. The effect reverses within about a decade. The mechanism is rates of return: wealthier heirs invest the principal and keep it, while others see it erode. The authors specifically reject the explanation that poorer heirs simply spend it. In the years right after receipt, roughly 70% of the extra annual resources went to consumption, about half of that to cars, rising toward 90% later, with the remainder showing up as reduced labor income.¹⁴

On the aggregate question the estimates are far apart. Palomino, Marrero, Nolan and Rodríguez put the combined contribution of transfers and family background at 36% in Great Britain to 49% in the United States, across four OECD countries, using a decomposition rather than a causal design.¹⁵ Feiveson and Sabelhaus estimated that intergenerational transfers account for 26% of total US wealth at a 3% real return and 51% at 5%.¹⁶ Black, Devereux, Landaud and Salvanes, using Norwegian data, reached the opposite emphasis: gifts and inheritances are a small share of total lifetime inflows and have very little effect on their distribution.¹⁷

The spread is not a reason to dismiss the question. It reflects real differences in what is being measured, in which country, over what horizon. Anyone quoting a single number from this literature with confidence has picked one.

How Summitward helps

Summitward does not draft estate documents and has no opinion about your trustee. Three things it does bear on the decisions above.

The retirement planner is where the “secure yourself first” constraint becomes a number. Running Monte Carlo paths with a long horizon and an explicit long-term care reserve tells you how much of the portfolio is committed to your own floor and how much is genuinely residual. That gap is the honest size of the opportunity fund.

The college savings planner sizes the capability floor against real tuition growth rather than a round number, and the multi-year tax projection is useful for the sequencing question, since the years when your own taxable income is lowest are often the best years to move assets.

Frequently asked questions

How much money is too much to leave a child?

There is no threshold the evidence supports. The best causal test of whether family wealth harms children found no effect on their skills or development, so a hard ceiling is not defensible on those grounds. What does have support is the timing and function of the transfer. A large residual bequest to an adult with established judgment carries different risk than unrestricted access for a 19-year-old, and the same dollars aimed at education or a business behave differently than dollars that underwrite consumption indefinitely.

Is it better to give money during my lifetime or leave it in my estate?

It depends mostly on basis and on your own security. Lifetime gifts carry your cost basis to the recipient under section 1015, while assets inherited at death take a stepped-up basis under section 1014. For a low-basis position held a long time, waiting is often worth more than gifting, especially for families well under the $15,000,000 federal exclusion. Lifetime gifts win when the recipient is capital-constrained at a moment that matters, when the asset has little embedded gain, or when you are above a state estate tax threshold.

Should I use an incentive trust that matches my child’s earned income?

I would not. Matching W-2 income pays the highest-earning career path the most and pays a caregiver, a graduate student, a public servant or a disabled beneficiary the least, which encodes market compensation as a measure of worth. Protective trust terms addressing minors, disability, addiction, creditors or exploitation solve real problems. Behavioral conditions mostly generate resentment and workarounds.

Does receiving an inheritance actually make people quit working?

It shifts behavior at the margin rather than causing withdrawal. Brown, Coile and Weisbenner found inheritance receipt raised the probability of retiring earlier than expected by 4.4 percentage points over eight years. Swedish lottery evidence implies a lifetime marginal propensity to earn out of unearned income between -0.17 at age 20 and -0.04 at age 60. Real effects, and a long way from the caricature.

At what age should I tell my children what we have?

Treat it as a ladder rather than a single disclosure. Concepts and household budgeting in childhood and adolescence, the broad shape of the family finances plus what support to expect in early adulthood, and full detail once they carry responsibility for any of it. The failure mode of total secrecy is an heir who first encounters a portfolio while grieving, with no practice and no framework.

Key takeaways

• Inherited wealth reduces paid work, modestly. Lottery evidence implies a lifetime marginal propensity to earn out of unearned income of -0.17 at age 20 falling to -0.04 at age 60; inheritance receipt raises early retirement probability by 4.4 percentage points.
• No causal evidence supports the trust-fund baby. When Cesarini and coauthors used random lottery wealth to test it, children’s scholastic performance and cognitive and noncognitive skills were essentially unaffected. Luthar’s correlational work on affluent adolescents identifies achievement pressure and parental distance, not bequests.
• Most of the transfer already happened. Black, Devereux, Lundborg and Majlesi found adoptive-parent wealth predicting adoptee wealth before any inheritance, with environment mattering more for savings and investment behavior than for human capital.
• Money raises life satisfaction more than happiness. Lottery winners showed sustained gains in how they evaluated their lives for over a decade, with significantly smaller effects on happiness and mental health.
• Timing and function beat size. The same dollar does different work at 18, at 30, and at 60, and a transfer that builds capacity is a different intervention than one that maintains a lifestyle.
• Check your state, then check the basis. Washington’s exclusion is $3,000,000 against a federal $15,000,000, and its rates changed twice in twelve months. Carryover basis on lifetime gifts frequently makes waiting worth more than gifting.

Editor’s note

Educational content, not investment, tax, or legal advice. Federal and Washington State figures are current as of July 2026 and were verified against IRS and Department of Revenue pages on July 28, 2026. State estate tax rules change frequently; Washington’s changed twice between July 2025 and July 2026. Academic findings are quoted from published abstracts and article pages rather than secondary summaries; where popular accounts of these papers differ from the papers themselves, the papers are followed.
