Money Identity Coercion Ego. Those are the primary motivators.

Being rich means you’ve solved money and probably coercion. You can either rest on your laurels or chase the other two, for good or for evil. There’s rich philanthropists - some who give almost everything away - and then whatever Elon Musk is, but most go for the rest on their laurels thing, and you probably haven’t heard of them.

Dehumanising someone also serves our identity and ego, FYI, which is where this thread came from.
