This is probably one of my hardest "right wing" stances, but I think this speaks volumes to my argument about this incessant push to make everyone go to college, and the problems that creates in society.
But in order to really solve this problem, we'd have to make jobs that don't require 4-year degrees more attractive and have to overhaul the high school system to teach those who don't want to pursue the 4-year degree the skills necessary to excel at these jobs.
Oh, and you have to sell American parents on the idea that little Jimmy might not be suited for traditional college, which is not going to be an easy thing (and realistically probably would cause every politician who proposes/supports this to lose any election, sadly).
