Student debt is mostly held by the richer half of the US population. Serious question: would it do more good if instead of giving money to people with student debt, you gave money to people without it? The first test of a potential policy is whether it's better than doing exactly the opposite. If you can't even prove that, it's probably not a good policy. https://twitter.com/paulg/status/1521112550770946048
Yes I went to a cheap state school that I could afford. I'm from a modest background and it didn't occur to me I could borrow beyond my means and go to a nicer school. I certainly don't feel student loan forgiveness is "fair" in that circumstance!
At this point I've paid my debts and still welcome relief for students who didn't have the same opportunities as me.
There is no 'cheap' 4 year school anymore. Costs can be mitigated by going to a Community College for an associates/first 2 years then bridge that into a 4 year program but if you want to go for research, engineering, or many other more dedicated programs then being at the 4 year school all 4 years leads to many more connections and opportunities that some feel are worth the cost.
Borrowing beyond ones means isn't always fully understood by a group of 17-18 year olds, especially those who may be first generation college students or from school districts that have spent 2+ decades now losing resources for educating students on college options in order to focus on the kids failing out. For example, many college apps I completed in 2011 needed a letter of rec from my counselor who I had talked to once as a sophomore but spent most of his time working with students on the edge of failing or dropping out. It's archaic just like how the US college system operates as a capitalists dream and not a public service.
In terms of fair, well policy hasn't been fair in a long time either. The 2017 tax bill raised my taxes and pushed a trillion plus surplus back to the wealthy - a much worse outcome for all then cancelling student debt without a deeper plan. It may not seem "fair" to you but that doesn't make it bad policy.
