Wealth taxes in America

I’ve been reading and thinking about the idea of wealth taxes. In principle, it’s an idea I could support. Too much wealth is controlled by too few in America today.

The chief argument I see made against wealth taxes is that they’re impractical. In a literal sense, this is easily falsified. We already have some targeted wealth taxes. Most of us pay them.

The most obvious wealth tax is real estate taxes. Homeowners pay them every year, and much of the money is used to fund local schools. The problem with real estate taxes is that they are highly regressive. For homeowners, property taxes are based on an assessment of the home’s value. But if you have a mortgage, you pay the full tax even though your equity in the house is less than the full value. And renters pay property taxes—your landlord passes their taxes on to you in your rent, even though you gain no equity through rent payments.

You may also pay personal property taxes on, e.g., your car, which is also a wealth tax, since it is assessed based on the car’s market value.

My point here is that we have some form of limited wealth tax already. The challenge becomes creating a progressive wealth tax that meaningfully discourages excessive* wealth accumulation like yachts, multiple homes, etc.

*Libertarians will ask how much wealth is excessive. I don’t know what a consensus would look like, but I’d be willing to stipulate as a starting point that nobody should own more than a billion dollars’ worth of property.
