The whole educational and professional training system is a very elaborate filter, which just weeds out people who are too independent, and who think for themselves, and who don't know how to be submissive, and so on, because they're dysfunctional to the institutions.
One problem with the way the educational system is set up is that it only recognizes a certain type of intelligence, and it's incredibly restrictive — very, very restrictive. There are so many types of intelligence, and people who would be at their best outside of that structure get lost.
Everyone is born a genius. But, if you judge a fish by its ability to climb a tree, it'll live its whole life believing its stupid.
