Arguing that the aim of everyone in capitalism is to escape from capitalism.

I think that idea has a lot of truth in it, but not 100%. To construct a single thing that nearly everyone in capitalism is trying to escape from, you need to put in more than just capitalism. You need to expand it to include the need to do work (whether for pay or not) and the constraints of living in a society with others. The billionaires are clearly aiming for all of that.
