Lots of the hexbears seem to be for eliminating the existing billionaires, so they can take their place.

Where on Earth did you concoct this fanfiction?

It also seems to be a big part of the crypto scene.

Why tie Hexbear, a firmly anti-crypto instance, with crypto?

As opposed to the MAGAts that think they will magically join the Billionaires if they elect those assholes.

MAGA is typically composed of Petite Bourgeoisie, ie small business owners and the like, that stand to increase profit margins via lower taxation, as well as socially conservative people. That's why fascism is rising in the GOP, as fascism is a class-collaborative ideology surrounding petite bougeoisie and bourgeoisie allignment against the proletariat.
