When “Tax the Rich” Becomes a Tax on Everyone

Democrats rarely stop at taxing the rich. They start there.

That is the real lesson from tax history. A tax is sold to the public as a narrow hit on a small group of wealthy households. Then the threshold comes down, the rates go up, inflation does the rest, and the burden spreads far beyond the original target. That pattern has played out before, and it is playing out again now.

A New York Example Shows the Problem

Bloomberg recently reported that Zohran Mamdani wants to slash New York’s estate tax threshold from more than $7 million to $750,000 and raise the top estate tax rate from 16 percent to 50 percent. New York’s current 2026 estate tax exclusion amount is $7.35 million. That means the proposal is not a minor adjustment. It is a dramatic move aimed far lower than the rhetoric suggests.

That is how these debates usually work. The sales pitch is always the same: this is only about the rich. But once the principle is accepted, the definition of rich starts moving. In a high-cost state like New York, a $750,000 estate tax threshold would not just hit billionaires. It would reach deep into family savings, small businesses, and homes that have appreciated over time.

Tax History Tells the Same Story

The original federal income tax is a useful reminder. When the modern federal income tax took effect in 1913, it imposed a 1 percent normal tax above a generous exemption, with the top combined rate reaching 7 percent over $16 million in today’s dollars. The tax affected only a small share of the population at the time. It was presented as limited and focused. It did not stay that way.

The same pattern showed up in other taxes that were supposed to be narrow.

The federal telephone excise tax began in 1898 to help finance the Spanish-American War. It was sold as a temporary wartime measure. Instead, Congress kept reviving and extending versions of it for decades. A tax created for a war that ended in 1898 lingered in one form or another well into the modern era.

The Alternative Minimum Tax followed a similar path. It was enacted in 1969 after it was discovered that a small number of high-income households had avoided federal income tax. But over time, because the tax was not fully adjusted and ordinary tax rules changed around it, the AMT threatened more and more upper-middle-income families until Congress repeatedly patched it and eventually indexed it. A tax aimed at a tiny number of wealthy households did not stay confined there.

The Obamacare investment tax offers another warning. The 3.8 percent Net Investment Income Tax applies above fixed income thresholds. That means more taxpayers can be pulled in over time even if lawmakers never vote for a rate increase or an explicit threshold cut.

The Threshold Never Stays Put

That is the central problem with every promise that a new tax will only hit the rich. The rate is only part of the story. The real danger is the threshold.

Once government creates a new tax base, lawmakers can always lower the point where the tax begins. They can leave thresholds frozen while inflation rises. They can add surtaxes. They can narrow exemptions. They can expand the tax in stages and pretend each step is small. But the final result is the same: a tax introduced as narrow becomes broad.

That is why proposals like Mamdani’s deserve scrutiny far beyond New York. Lowering an estate tax threshold from more than $7 million to $750,000 is not just an aggressive tax hike. It is a case study in how fast “tax the rich” can become “tax more people than advertised.”

CFE Takeaway

Never take “tax the rich” at face value.

History shows that taxes marketed as targeted often expand. They hit more households, more savings, more investment, and more families than promised. The first target is the rich. The next target is everyone else.
