The problem is that the constitution doesn't allow for a wealth tax. If you remember, we had to pass an amendment to be able to levy a tax on income, and that amendment is clear in that it only applies to income.

Interestingly, it was also promised to be only 1% or so on the richest households, and it has become, er, different.

But more important to the point, as the government already taxes about 20% of income, that is equivalent to holding about 20% of the wealth, as the wealth is just an income generating device and the value of the wealth is the flow of income it generates, of which 20% is already taxed.

What I'd like to know is why people are obsessed about stocks and flows in completely different ways. For example, not caring about the deficit but worrying about the debt, or vice versa, or focusing on taxing wealth but not really caring about taxing income.

I think the idea of taxing income makes a lot of sense, and don't want the government to try to value assets, particularly illiquid assets. And if it was up to me, I would dramatically simplify the tax code to eliminate all deductions and tax all income at the same rate, regardless of source. No reason to have one tax rate for carried interest, another tax rate for dividend payments, a third tax rate for wage income. Treat all income the same, and apply a progressive rate to the total income. Your tax form should not be more than a page long.
