This would save young Americans from going into crippling debt, but it would also make a university degree completely unaffordable for most. However, in the age of the Internet, that doesn’t mean they couldn’t get an education.
Consider the long term impact of this. There are a lot of different ways such a situation could go, for better and for worse.
What issue are you looking to solve? You state that you believe people are able to seek out, and attain their education independently through resources like the internet. So why would it matter if there are alternatives that cost money which one can pay, and receive loans for?
It matters because American culture currently prefers everyone to have a college degree as opposed to any other type of education. Loans exist to allow the poor to “keep up with the Joneses” for a few years and then yoke them into debt for the rest of their lives. If this avenue was cut off then the attitude of the public would change to allow other means of education.
