it's not unhinged at all. he's deeply mortgaged on many real estate holdings. inflation increases the nominal value of those holdings, while the mortgage payment stays fixed. inflation increases cash flow because he can charge higher rents.

he's stupid enough to accidentally trigger hyperinflation, but creating moderate to high inflation is entirely within his rational self interest. he doesn't give a shit what it does to anyone else.

He knows he's never leaving office is what he knows. His supporters don't care.
