This comes from the same mentality as people who skip vaccinating their children: we have a generation who grew up taking things for granted, so they feel free to reject the very things that gave them that privilege. Grow up without being surrounded by disease, and it feels safe to throw away vaccines. Grow up taking an educated populace for granted, and it feels safe to throw away college.
It's also the same mentality that leads people to stop taking medications. I've seen so many people with seizure disorders stop taking their pills after a time because they don't have seizures anymore..... then immediately have seizures again. I know one person that died as a result of this.
As a person who has gone to college, dropped out, and is now going back, I understand the value of the education and experience. It's not for everyone, but it really does have immense value. Very few people have the disposition and dedication to focus themselves and spend their time doing something better than college - most who drop out or don't go will spend their time doing something far less valuable.
