Wow. Those numbers are higher than I thought. My impression was that the percentages who go on to academic (not including vocational) university education was in the teens. This is based on family in Switzerland, but the data is probably stale at this point (1980s).

I should point out that I'm not against a third or half of Americans getting some kind of free higher education. I just think it's a waste for them to have an academic education, when only a minority of jobs require one. Appropriate vocational training would be better.
