We are not arguing about the cost of education because students can't pay the tuition; they pay the tuition every year with no problem even though it keeps rising. The argument is because after they graduate they have a mountain of student debt. Students have a debt problem not a tuition problem. Colleges will keep raising prices as long as the students keep paying them because that is how markets work.

Loans have enabled all those "changes in education finance", all of them. You don't need to have 100% reach to influence a market, you don't even need to be technically in the same market to influence another one (see smartphones and taxis).
