I feel like he would just buy his luxury in prison like Pablo Escobar.

I think the worst punishment for people like Thiel and Musk would be to have their assets seized and any future wages garnished to be paid to the victims of their crimes, while they’re forced to attempt to survive in the society they’ve helped create.

The consequences they face will serve as an example and deterrent for others like them and one of two things would happen. Billionaires suddenly experience empathy/gain a conscience and conditions improve for all of society, or, billionaires continue to maintain the conditions they’ve created while one by one falling victim to their own creations. Most likely they check themselves out very quickly rather than attempt to survive the nightmare they had no problems inflicting on others. Either way equals a net gain for society.
