College used to be for the top 10-15% of people. Decades ago, we just didn't NEED that many college graduates. In my own case, I went to college (1) because my parents INSISTED (and paid for it), and (2) to stay out of the Vietnam War.
I didn't go to college to prepare for any particular job. I think my college experience and learning have enhanced my life, but I could have made as good a living as an electrician or a plumber or welder or machinist. When you learn a real skill, a marketable skill, that skill is your most valuable asset! That skill pays for everything in your life!
Everyone wants to go to college these days, even despite the inevitability of racking up tens of thousands in debt. But college and vocational school are different, learning abstractions and different ways of thinking vs actually learning to DO something. I'd think a decent vocational school would be easier, and more enjoyable too, for most people.
