Redirecting all wealth above $100 million that the richest have could fund the many infrastructure upgrades the U.S. needs.

But wealth extraction would forced asset sales across the economy, potentially depressing stocks and other markets and decreasing the value of regular Americans' retirement accounts.

Economists say infrastructure works best with steady, predictable funding—not one-time windfalls from massive wealth seizures.

A recent AskReddit post posed the following question:

If all personal wealth above $100 million was legally required to be redistributed into public infrastructure (schools, hospitals, roads), how would society change, and who would be the first to fight against it?

More modest proposals are being debated across the U.S. For example, Massachusetts voters approved a 4% surtax on income over $1 million in 2022, which raised almost $3 billion for schools and transit in 2025. California has a ballot initiative that would impose a one-time 5% tax on the wealth of billionaires. At the federal level, Senator Elizabeth Warren's ultra-millionaire tax would affect fortunes above $50 million.

So what would happen if we went further and redirected all wealth above $100 million to public infrastructure?

How Much Wealth Are We Talking About?

Federal spending on infrastructure totaled about $125 billion in 2023, the last full year of available data. Add in state and local governments, and the U.S. spends about $626 billion annually on such things as roads, expanding broadband access, and water systems.

Though that may seem like a lot, U.S. infrastructure spending isn't keeping up with America's repair needs. According to a 2025 report by the American Society of Civil Engineers (ASCE), it would cost $9.1 trillion to bring the nation’s infrastructure to a state of good repair. Even if today's levels of funding were maintained, ASCE says there would still be a gap of $3.7 trillion over a decade.

What matters most for answering the Reddit question is whether the wealth that could be collected could meet America's infrastructure needs. The Federal Reserve doesn't track centimillionaires in particular, but reports that the top 0.1%—about 135,000 households with at least $47 million in net worth—have a collective net worth of more than $23 trillion. The wealthy in this group have an average net worth of about $172 million. Even if centimillionaires form only a subset of the top 0.1%, they'd still have more than enough to cover America's growing infrastructure tab.

The Infrastructure Wishlist

If much of the superwealthy's money were redirected, roads, bridges, and transit systems could be modernized at scale. Aging water systems, including lead pipe replacement, could be accelerated nationwide. The electric grid could be made more resilient and upgraded to support renewables. Rural broadband gaps could close faster. A new layer of infrastructure that's needed could be more fully funded, such as AI data centers and cybersecurity systems.

Infrastructure spending also has multiplier effects. Investments in transportation, energy, and water systems often boost jobs, productivity, lower long-term costs, and support regional economic growth. On paper, the benefits are substantial.

But It's Not That Simple

The wealth of ultra-high-net-worth individuals is tied up in businesses, real estate, and stock—it's not cash sitting in a vault. Forcing large-scale asset sales could disrupt financial markets, triggering volatility and valuation declines that would affect everyday people and their retirement accounts and pension funds.

Net worth also swings with the market, which can add or erase tens of millions on paper without any change in a wealthy person's cash flow. Capital flight is another risk: the wealthy could move assets abroad. Administrative complexity adds another hurdle: valuing assets, enforcing compliance, and allocating funds effectively would require a far larger enforcement apparatus than the IRS has now.

The Economic Trade-Offs

Larger investments in infrastructure would create jobs and support long-term growth. Higher taxes would narrow the wealth gap.

On the downside, extracting so much wealth at once would reduce the private investment that funds startups and research for medicines and new technologies. Market disruptions could hurt workers and consumers far from the ultra-wealthy. Legal and constitutional challenges, too, would slow any systemic changes.

The Current System for Funding Infrastructure

Gas taxes, tolls, and general revenues pay for most infrastructure in the U.S. The federal government covers about one-quarter of highway and transit spending; state and local governments fund the rest.

Public-private partnerships, while growing, still account for only about 1%–2% of U.S. infrastructure investment.

Infrastructure works best when financing is steady, not dependent on one-time windfalls. Building a road is one thing; making sure its potholes get repaired for years down the road is another.

The Bottom Line

Seizing wealth above $100 million could transform America's infrastructure. However, it could risk a cascade of unintended consequences. Therefore, an important question isn't necessarily how much money exists at the top, but whether it's possible to forcibly redistribute it without damaging the wider economy.
