Income tax didn’t exist in the United States until 1913. When it arrived, the top marginal rate was 7 percent, and it applied only to people earning more than $500,000 a year, roughly $12 million in today’s dollars. It was, in other words, a tax aimed squarely at the very rich.
That didn’t last. Once governments discovered how much revenue a wealth tax could generate, rates climbed steadily across the developed world. Britain pushed top rates above 90 percent by the 1960s, and the result was what became known as the “flight of the millionaires”: the British film industry relocated to Hollywood, and the Rolling Stones decamped for the South of France to escape the tax bill. France soon matched, then exceeded, British rates on its own wealthy citizens.
Why tax rates eventually stop working
At some point, rates rose past the level where they were actually productive. As taxes climbed, the wealthy responded the way people generally respond to bad incentives: they retired early, relocated, or stopped investing. Capital left. Incomes fell. And because income and capital gains are what get taxed, tax collections fell right along with them.
Economist Art Laffer’s famous curve captures this dynamic: there’s an optimal rate of taxation, and pushing rates higher or lower than that point actually brings in less revenue, not more. Most developed economies have since brought top marginal rates down from their mid-century peaks, on the theory that they’d found roughly the highest rate that didn’t suppress the tax base itself.
The seventeenth-century French finance minister Jean-Baptiste Colbert put it more bluntly: collecting taxes is like plucking a goose, and the goal is the largest number of feathers with the least amount of squawking.
The case for taxing the rich, and its limits
The argument for higher taxes on wealth usually rests on two claims: governments need the money, and it’s fair. On the first point, there’s not much to dispute. Developed nations carry enormous debt loads, and aging populations mean promised pension, healthcare, and education benefits will be hard to fund without new revenue.
But the second half of the argument deserves more scrutiny than it usually gets. Taking money from the people whose capital funds new businesses and new jobs, and handing it to government to allocate instead, only makes sense if you believe government bureaucrats invest capital more wisely than the people who earned it. History gives little reason to believe that. Government operates outside the price system: nobody gets to vote with their own money on whether a dollar goes to a fighter jet or a school, so there’s no market feedback mechanism telling policymakers when they’ve made a bad call. Resources invested well produce more resources, and everyone with a stake in that pool of capital benefits. Resources funneled into unproductive uses just make the world poorer, regardless of the good intentions behind the policy.
What this means for building lasting wealth
None of this means taxes are avoidable, or that legal tax mitigation is somehow improper. It means a family serious about preserving wealth across generations has to treat tax exposure as a permanent line item, not an afterthought handled each April. The tools for managing that exposure, entity structure, trusts, timing of gains, are worth understanding well before you need them, because tax policy shifts with the political winds and the families that plan ahead are the ones who keep more of what they build.
