On one hand, culturally, we pushed young people into colleges and universities at ever-increasing and frankly unethical price points. Many people have spent "buy a house" money on education. These people are then given a heavy burden which holds them back significantly both socially (raising families) and financially (owning a home, saving for retirement).
On the other hand however is the many people who decided not to go to school because it was simply unaffordable. They went to work instead, and often in the kinds of careers that are unappealing to college graduates who prefer white-collar work. Any student loan forgiveness is coming directly from the pockets of these people, who have on-average lower incomes and shorter career spans than their white-collar counterparts.
It's easy to see both sides on this one. The only meaningful solution I can see is to remove the (again, unethical) protections which prevent students from declaring bankruptcy over student loans. In turn, this would hopefully force wiser lending and more price-competition to bring the cost down.
