I really wonder why so many of the super-rich back Trump. He has a really bad track record when it comes to honoring contracts, let alone promises. Add to it that he already tried to overthrow democracy, in which case your campaign contributions would become worthless the moment he manages to seize power.
Dude, Trump got them their tax cut. He gave them billions in shady covid money. He appointed anti union judges. He's done a phenomenal job for billionaires, just like every Republican president.
What I mean is that he clearly has ambitions to become a dictator, as seen when he refused to peacefully step down after losing the last election. The power billionaires wield comes from their ability to use their money to influence elections. Once there's no more free elections, the billionaires have a much harder time applying political influence, and doing so may get them killed. Compare the list of notable Russians who died under suspicious circumstances
They are fascists, the whole bunch, and see Trump only as a pawn. He is almost 80 and will die in a few years anyway. Once they broke the system for good, some killing happens here and there until someone with the strongest backing settles in at the top. That's how the Nazis did it in the '30s (e.g., killing the leaders of SA and political opposition), that's how it works in Russia etc. I guess if you're rich enough, at some point you believe you're going to be the one doing the killing and not the one doing the being killed by others (again, look at Russia for recent examples or here:
On a deeper level, I think the split happens between people who fundamentally think all humans are equal and should be treated accordingly, and people who think there are more and less valuable humans and the valuable ones should assume power over the others. To become a billionaire, you need to ignore the fact that you can use your money to make a real difference for others who are suffering, and instead you focus on accumulating more.
