So you think that everyone has the same abilities and we all start from the same position? And that everyone can simply find their own unique role? You are generalizing too much... things don't work that way.
We don't have equal abilities, and for sure, we don't have equal chances... And you wrote it like it's wrong to invest in Bitcoin. Why? There are a bunch of us without some special talent, and some invested in BTC early on... even that is some kind of talent & courage, to see what's good and give it a try.
It's the opportunities that is the hardest one. Because humanity can't afford to give every child the same opportunities, it is not even about "good schools vs bad schools" because there are plenty of schools which was built to make sure only the rich people's kids go to, and education there is horrible, in the literal "learn chemistry and math" kind of way, it's only built to make sure they educate leaders.
Hence, they do not learn math or geography, they learn about people management, and that is done by wasting time building connections, and this way rich kids, grow up with rich kids, but they stay stupid on things that matter. So the opportunities part matters a lot and even if you are rich, send your kid to somewhere they can learn.
