Billionaires aren't going to passively ride it out. They know that if they do nothing and the left wins, the bunkers will be sealed with cement and that will be the end of them.
Fascism, autonomous weapons, and autonomous industry are being set up so that billionaires get to remotely depopulate the Earth and control who survives and with what ideas, so that when the dust has settled they are still billionaire kings. They're going to use white supremacy like they've used it the past centuries.
If we are fighting billionaires, we are either seconds away from winning or we are fighting their white supremacists goons. That will be true regardless of how well we understand that those white supremacists are mere tools for billionaire greed. Maybe we can convince some of them to switch sides, but it would be foolish not to prepare to fight white supremacists. That would require expecting every white supremacist to stop acting white supremacists when, historically, millions of white supremacists have fought and died to line billionaire coffers.
