Isn't at least part of the problem the exorbitant high cost of college education? This will cause the price of college to spiral higher and higher, since students can just sign away a larger portion of their future earnings. I've heard that higher education is free in Germany, even for foreign students. Couldn't we implement a similar model here in USA?
