This is what happens when the government interferes with the free market! The supply of virtually unlimited, guaranteed federal loans has created a moral hazard. Loan companies don't care to hand out risky loans because they have the backing of the federal government. Since students have access to so much "free" money, they are entering colleges in droves, effectively bidding up tuition prices for the rest of us. Without such a supply, loan companies would be much more stringent (tuition would come down) and some students would not be able to enter college. While this may sound bad, its not because certain college degrees are becoming worthless anyway and some students have no business of earning degrees in human resources management from the University of Phoenix.
I agree that it is somewhat useful to have these ancillary classes such as marketing, finance which would complement well with a degree in engineering i.e. computer science, materials science, biomedical etc.
