the fucked up thing is that it's almost true, there's a level of wealth where people are generally optimally happy. Look at people who get enough money to buy a house and comfortably retire early on without needing to worry about affording normal things again, something like that is peak contentment in life.
I sincerely do not understand why a mentally healthy person would ever want a to be richer than that, it means you have to do a bunch of publicity shit and other miserable stuff and it doesn't really benefit you much.
