My problem with a wealth tax is that it is proposed as cure-all for income inequality. As if that wealth was ill-gotten and unfair.
The wealth tax is also advanced when, at the same time, expensive NEW programs are championed that would eat up any short term gains.
I have ALWAYS had a problem with the carried interest provision in the accounting of hedge funds.
I have also felt that there should be one more higher tax bracket for the super wealthy.
And a capital gains tax increase for capital gains realized over some set amount--to the ordinary income rate. Modest capital gains would be taxed at the current rate to preclude lower income investors from paying taxes at the higher rate (many seniors of fixed income may finally sell some of their retirement assets after years of saving and they should not be taxed at the high income tax rate).
Those super wealthy whose income is largely from capital gains would be taxed at the income rate.
But the cynical ruse to suggest that we can write off college loans, do Medicare for All and the Green New Deal if we do a wealth tax---well, you can smoke it in many states now that it is legal.
