>Once a new tax is imposed, its limits and brackets are probably the easiest things to change about it.

Just introduce a tax on money held in bank accounts. Doesn't matter if its above $100k or $1 million.

>Moreover, if they aren’t inflation-adjusted, the Fed will make sure we’ll all get there pretty soon, just by printing money like they are doing these days.

When people are stupid enough to "invest" into money you run into an obvious problem. The supply of money is limited. Every dollar that is being saved makes it harder to save the next. So you have to create new money as people save money. The conventional way is to run a government deficit. The better way is to stop regressive saving in money by introducing a negative interest rate for big accounts.

Investments don't matter. Even if the rich HODL all existing stocks someone can start a new company that you can invest into. Old businesses can also issue new shares without people being angry. None of this is zero sum. But saving money? Oh boy, that is the most zero sum way to "invest". The only reason the system hasn't collapsed is that the Fed is making sure that every time a dollar is being hoarded there is a new one to replace it.
