The Inheritance Economy — Macro Drag on Growth
When parental wealth is the primary gateway to adulthood, the whole economy stalls — not just the unlucky individuals.
The inheritocracy is not just an inequality story — it is a growth drag. Filby argues that when parental wealth becomes the primary route to the big-ticket items of adulthood, the entire economy loses efficiency. The housing market clogs: 51% of baby boomers live in homes with more than two spare bedrooms, holding property wealth that does not circulate. Workers are demotivated: if wages cannot buy what they bought a generation ago, the employer-employee contract breaks down at its core. Young people rationally redirect energy from employer loyalty toward side hustles and inheritance speculation.
The three things that Millennials spend money on — eating out, technology, and travel — became cheap precisely because the economy incentivised their consumption. The three things they cannot afford — housing, education, and childcare — became expensive because the structural levers that kept them affordable (social housing, free university, public childcare) were dismantled or defunded. The cheap things and the expensive things are not accidental; they reflect decades of policy choices that disproportionately benefited older cohorts.
The inheritance tax system amplifies the drag. Only 4-6% of estates currently pay inheritance tax, and those that do can largely avoid it with competent advice. The 2024/25 budget began closing loopholes — taxing inherited pensions, tightening business property relief — but the scale of the £5.5 trillion housing wealth transfer suggests these measures are modest relative to the structural issue. Filby does not argue for punitive inheritance taxation; she argues for an economy where inheritance matters less because wages, housing, and education have been rebalanced.
- An economy where the primary route to asset ownership is parental wealth is an economy that has structurally severed the link between work and reward.
- The UK's £5.5 trillion housing wealth concentration in the over-60s is simultaneously private family wealth and a systemic housing market dysfunction.
- The cheapening of consumption (eating out, technology, travel) and the expensiveness of asset formation (housing, education, childcare) is not accidental — it reflects two generations of compounding policy choices.
- Workforce motivation requires a credible wage-to-assets pathway; when that pathway closes, employer-employee trust breaks down regardless of other benefits.
- Inheritance tax reform alone cannot solve the inheritance economy — wage growth, skills investment, and housing supply are the structural levers.
- Map the consumption vs asset formation split in your contextIdentify which goods and services have become cheaper (consumption) and which have become more expensive (assets) over the last 30 years in your market. The pattern reveals where the economy has been structurally incentivised and where it has been structurally neglected.Pro tipIn the UK: eating out, flights, smartphones — cheap. First home, university education, nursery places — expensive. The ratio has inverted relative to the 1980s.
- Analyse the policy levers available and their realistic scopeInheritance tax reform, wage growth policy, skills investment, and housing supply each address different parts of the inheritance economy. Understand which lever addresses which dysfunction before evaluating any policy proposal. Inheritance tax reform without wage growth leaves the core driver intact.Pro tipFilby's view: inheritance tax loopholes closing is necessary but not sufficient. The bigger levers are wages and housing supply, both of which require sustained multi-decade political commitment.WarningPolicy that targets only the symptom (inheritance concentration) without the cause (wage stagnation, housing supply constraint) will produce backlash without structural improvement.
- Understand the multigenerational household trend as an adaptationRising multigenerational living — granny annexes, adult children at home, in-laws contributing to childcare — is a household-level adaptation to macro dysfunction. It is also a signal: when formal markets fail (housing, childcare, social care), informal family markets expand to compensate.Pro tipIn cultures where multigenerational living was never abandoned (South Asian, Nigerian, Eastern European), the adaptation is less visible as a shock because it was never absent.WarningThe rise of multigenerational living reduces measured housing demand without reducing actual housing need — it can mask the severity of the underlying housing shortage in policy data.
- Assess the workforce motivation implications for your organisationIf wages in your sector cannot purchase housing, employees will rationally prioritise inheritance expectations over employer loyalty. Survey whether your workforce has realistic wage-to-asset pathways and whether your employer value proposition assumes a meritocracy that your employees know no longer fully operates.Pro tipFilby visits companies that report motivating young staff is difficult. Her diagnosis: the implicit contract that hard work leads to material security has visibly broken down. Addressing this requires more than a pay review.
51% of UK baby boomers live in homes with more than two spare bedrooms. These rooms are largely unused except when adult children return for holidays. The property wealth those homes represent is illiquid, not circulating in the housing market, and occupied below capacity.
Filby names the inversion explicitly: the three things Millennials are culturally mocked for spending on — avocado toast, lattes, travel — have genuinely become cheaper in real terms. The three things they cannot afford — housing, education, childcare — have become genuinely more expensive. The cultural mockery inverts the economic reality.
The UK's 2024/25 budget began taxing inherited pension pots and closing business property relief loopholes — the first significant moves to widen the inheritance tax net in a generation. Currently only 4-6% of estates pay inheritance tax.
This macro argument emerged from Filby's micro-level research. Pattern by pattern, interview by interview, she noticed that individual struggles aggregated into a structural story: an economy systematically tilted toward older cohorts by decades of compounding policy decisions. The book's macro argument is the inverse of the personal stories — each individual experience of blocked mobility is also a unit of economic inefficiency.
