If you have that kind of money, why would you not just take it elsewhere? Think about it, if that capital is actually creating returns to make up for the depreciation, it must be working capital. Removing it from the economy would be damaging.
What if the money is in government bonds? Those return below 1% right now, so you just dump them, putting more pressure on the Fed to keep stable rates.
Which brings us to the next topic: Dollar depreciation. You already need ~2% returns just even out the CPI inflation rate, but asset inflation is way higher than that.
So you're basically begging rich people to dump dollars, dump US bonds and move working capital to safer countries. Good Luck with that.
