What if that someone is average and lazy in their work to devote the rest of their time to their family? What if they raise a bunch of kids that love their parents, care about each other and the world and want to make it better? Would that be success?
What if they were molested and use drugs to cope, but live their entire life without molesting anyone else? Would that be success?
What if they have serious depression and they check out by playing video games, but they don't kill themselves? Would that be success?
Holding up a few spectacular achievements as the paragon of human experience is fucking stupid.
I genuinely think really rich (and smart) people do it to try to salve their guilt and signal for others.
