The other financial factor that can't be ignored in US politics is cryptocurrencies. The amount of money now invested in crypto is insane, and around 28% of US adults have some crypto investments. For a lot of people it's tied in to a whole worldview - libertarian, techno-utopian, anti-government, and pro-Trump largely because they think he's pro-crypto. There are some wild views out there - a lot of people apparently believe that in due course Bitcoin will become the primary global currency, with a single Bitcoin worth a billion or more.
But these are wildly unreliable investments with zero real value - the biggest market bubble in history - and it's highly likely that in due course a lot of people will lose a lot of money.
I think that crypto and MAGA are deeply intertwined, not just practically but psychologically - all about belief in something utterly unsupported by reality. I think both bubbles will eventually burst together in a very messy way.
