Do you need to earn your own wealth though if you've already came from a wealthy family? It's like kings and queens in the past.. They didn't force their children to work. They were the heirs and took over the wealth, which is how it should be and has been that way for thousands of years, all of human history. Only now are we supposed to work a 9-5 in order to be respected it seems.
I just don't think they necessarily needed handed $600 million when it could be used for other things.
I'm on several wills so I mean I can't speak as if no one deserves an inheritance but there's no necessity to be grossly rich
