That works for some career fields, especially IT, but not most.Government loans are why tuition costs are so high. When you subsidize a service, the provider raises prices because they have a guaranteed price floor.
If you want to lower education costs, you increase competition and get government out of the loan business. This is actually happening now with the rise of online schooling and certification programs.
Part of the arguments regarding college now and why people are waking up is the cheaper cost of the aforementioned. We see how bullshyt administrative costs are used to justify high tuition prices for brick and mortar campuses. So, just go to a cheap online school, learning platform, or use free resources and get the degree/cert for a fraction of the cost in terms of time and money.
As for there being a price floor, I don't disagree. However, I still haven't seen anyone explain where the overcharging is occurring at the average state school.
