This is a good, nutshell explanation of late-stage capitalism.

As far as the answer to “what’s the endgame”, I do not know. I suspect that many or most of these rich folks are so moneyblind that they don’t know either. Or, they simply don’t believe that their collective actions will eventually cause the system to fail.

But most likely, I think, is that they believe someone else will bear the majority of any negative impact. Of course this makes less sense in the face of a systematic collapse, but again: it’s probably very difficult to see when you have dollar signs in your eyes.
