I don't think all of them have an inability to understand class, that's why their thought-leaders highlight these enemies are billionaires at all, because there is a latent deep down issue many of the followers have with the wealthy, otherwise they wouldn't even highlight the huge riches. The problem is it's buried in as you point out massive amounts of total incoherence and brainworms. They have become pawns of the political leadership that has managed to snag them. In my opinion slightly different political conditions would have parts of this crowd become communists, but with the same level of complete and total incoherence (which would be fine as they'd still be led by the political leadership). Unfortunately that's not the case.
