No matter how many loans or funding you get, it'll always be impossible for everyone to go to the top 50 schools, unless you simply outlaw all schools outside of the top 50.
That is not the point. The point is that kids whose parents cannot pay/cosign a loan can currently get into the top 50 schools but without the government backing the loans, none of them would likely be able to get in at all leaving the top schools only for rich kids.
Nope, that is not how unsecured personal loans work. Those depend on your credit which most students don't have much/any and your debt-to-income which is normally infinite for students because they don't work.
