One way to destroy the “wealthy” is to reduce the value of their accumulated assets. Inflation does exactly that.
I remember some article talking about how the Russians and Vietnamese allowed hyperinflation because it made everyone equally poor.
Inflation only destroys currency (in our case dollar) denominated wealth. If you have non-cash assets you can come out of inflation pretty well. And if you can buy a lot of property with fixed-rate loans and have inflation essentially wipe out the loans for you, you can come out way ahead.
I've heard stories about people going through bouts of hyperinflation in South America where the stamps to send in mortgage payments cost more than the mortgage payments did.
