The vast majority of debt for people under 125k/yr who qualify for the 10k relief is the interest, not principle. The forgiveness is then effectively for a tax in this case, not the actual loan, when you think of it like this.
The federal government designed the federal loan program to make them money, based on interest. It has panned out as a very stupid fucking idea, in retrospect, and has made millions of people debt slaves for years on end. They set themselves up for this, combined with stagnating wages, making everything a joke. Everybody wants to talk about bailouts and "work ethic" but seemingly forget the monetary policy was set and managed by the federal government over the past several decades. They could have done better policy if they didn't want a bunch of bullshit.
It has nothing to do with work ethic, at the end of the day. It was a policy decision from on high, and the snowball was set in motion probably long before you even went to school.
