I agree with this author.
It seems that going to college replaces the potential income from working with loan debt. Previous generations didn't need college to make a career, and since high school was free via public funding, they had a leg up. It seems there's an argument somewhere for the public to subsidize state colleges more, which may help young people and the economy overall.
That being said, I think parents and teachers have a responsibility to give high-school students the facts about what college will do both for them and to them. I recall being in high-school and being told that college is the cure-all for anything and everything. I wonder if this message is still being promulgated and how millenials' children will view higher education. Will that generation be less educated?
