It makes perfect sense once you understand money is a hard drug.

No one needs this much money, they could be living a quit happy fulfilling life but instead all they do is try to obtain more, at the expense of social relations, their family and their own mental health. They destroy their own lives to get the dopamine hit of the numbers going up.

People like Elon are addicts. Greed is an illness but rather than giving these people medical help to stop hoarding excess wealth we glorify their problem like their winning.
