I mean, if you're starting from the view that we have too many poor people for the number of billionaires, then killing off a bunch of plebs in a massive economic depression is definitely one way to balance the field. Just seems a little psychopathic to me, is all.
It's definitely a MAGA theme, though: let bird flu run wild and all the survivors will be immune; crash the economy and all the survivors will be better off; throw out all the immigrants and every that remains will be comfortably English-speaking; jail all the protesters and everyone that remains will agree.
That's income, though, not net worth. Imagine you've got $250k in your 401k and you spent $250.
