The likes of Thiel, Musk et al are like old-fashioned Marxists in that ..... now bear with me here!.... that they think a neo-feudal order will come about whether anyone likes it or not.
I'm sure they want to be the lord rather than a serf, but the point is that they think this is inevitable.
There was a lot about this in the BBC podcast The Coming Storm series 3.
Trump? I don't think he's really interested in all that. He has a more old-fashioned agenda and I think his bromance with Musk will only last as long as it's convenient for both of them. I think Trump is doing this for his own reasons though I'm sure others are egging him on.
I'm not sure where Vance fits in to this Trump / Musk axis of idiocracy.
