In your experience? The world over? Can you tell me your experience. I've been a teacher for a long time. I've worked in the UK, the USA, PNG, and Kenya.
The vast majority of kids in the developed world don't really care about education. A few do, and they get great grades. Most care more about social status, their cliques, or just surviving the jungle that is school.
School is important. It teaches you how to deal with other people. It teaches you how to deal with people in authority. You can't get that at home, in front of a screen. Learning stuff is secondary. I'm sure there are plenty of people here that are not working in whatever they majored at.
