It's crazy to cancel student loans and still keep issuing the exact same loans. If we believe the loans are unjust then the government should stop handing them out as the very first step.
This loan forgiveness is for a very specific subset of lenders who have been making payments for 10 years but not yet paid of the loans. Eliminating loans all together would not have put them or society in a better position, it would just mean that next semester there would be hardly any new students accepted at any higher education and the entire education sector in the US would be bracing for impact and trying to figure out how on earth they are going to continue while their normal revenue disappears overnight.
If anything would be crazy, that would be it.
