Govt pays large sums to liberals in universities, through the students.
The money changes hands and votes are bought.
Students are left holding the debt....unless they are forgiven, in which case the taxpayer holds the bag.
Nice scheme if you can tap into it.
The parabolic rise coincides with Obama regime in charge. So there is a lot of truth in what you are saying.
In addition, students are indoctrinated into leftist thinking, which also creates votes for the Democrat party and perpetuates the system.
