Part of the problem is that sufficient wealth seems to destroy people’s understanding of consequence. They don’t experience them very often, and so reach a point where they can simply pursue whatever their feelings tell them to do and the world magically restructures itself to allow them to do so.

Combine this with how the incentives of the social system result in the people who are most likely to pursue a selfish course being the most financially successful- you get a recipe for short-sighted, ignorant and self-important nonsense.
