Tuition costs have risen 710% since 1983
Makes sense when you have student loans backed by the federal government. If an 18 year old with no money and no credit history gets accepted into a qualifying university, she will be able to receive a loan since the bank knows that the government will protect their investment if she fails to pay them back. So now young people have this easy access to credit, and universities can greatly increase tuition and fees with the confidence that their admitted students will be able to pay.
