Four year college is not necessarily for everyone and there's far too much emphasis in the United States on everyone (or at least more people every year) getting four year degrees. To put it crudely, society needs people who clean floors and flip burgers. And I don't mean that in an elitist sense, but as a simple statement of fact. And those people don't really need to go to college. Hell, they don't even really need a high school diploma.
Kain argues there should be more quality vocational training at the high school level. I agree.
