I have come to the realization that for most people paying for their. Childrens education is almost impossible. The most important thing is to Insist the student to get a degree where you graduate with a skill. Primarily science and related degrees. 80% of kids graduating from college don’t know anything more than the day they started college. This is a problem.
I won't address your 80% figure, but college is like anything else. You get out of it what you put into it. A few people seem to think that their job is just to show up (often late) and wait for someone to unscrew their heads and pour knowledge into them. There are other people who spend their lives learning, both in and out of school. College was good for me.
