The alternative is that you end up with nonsense like hungry grads working at FAANG to fuck the world.
Channeling people into useful pursuits pays dividends.
It is not about society’s accommodation/assistance of specifically the gifted but rather about ensuring that people of all conditions can develop their potential. Society should care about this because it’s the long-term flywheel that improves the human condition.
The pie can get bigger, too. It’s not just about dividing a fixed pie most evenly.
The practical world is full of interesting problems. Gifted humans need to really feel useful (to put their gift at use) more than they need the matching income.
furthermore, there may be a lot of overlap between useful/important and interesting work, but I doubt they map perfectly. there probably needs to be some material reward for important work so that it gets done even if it's boring.
I certainly don't think we have a great state of affairs today. some people get paid huge amounts of money to do work that I feel is harmful. imo the goal should be to take care of everyone's basic needs, but also to reward people proportionately for their contribution to society.
