I don't think there is a single concrete goal, when you look at how flabbergastingly stupid most of the oligarchs are (just scroll through Elon Musk's most recent posts) it's hard to imagine there being any real master plan. It's a bunch of dumb assholes that were raised with infinite money and where nobody ever told them no.

If you've ever had the unfortunate opportunity to interact with your average CEO at a mid-level business it's the same thing but on a much smaller scale. They can't fail, only be failed.
