It's only a contradiction if you view the world extremely antagonistically — that Musk and Bezos have the prime and only goal of sitting on top of a pile of cash while the world burns around them.
If you see the world as Musk and Bezos building and deploying capital to build what they see as a better future, there's no contradiction at all. There's fierce disagreement about how we get to that future, but we all want the same general thing.
Agreed. It's a logical fallacy. The article seems to cynically assume anyone who achieves great wealth must de-facto be in favor of the system that got them there, and couldn't possibly wish to build a more ideal world without being in contradiction with themselves.
It’s an odd quirk of the average socialist/communist that they deride any individual attempting to improve the world while causing some negative economic side effects but they applaud totalitarian governments that take a stab at communism and murder millions of people in the process
