There's a balance here. We have laws against predatory lending for a reason. I'm not saying that we need to just give away total debt forgiveness, but I also want to make sure I point out that the lending strategies are predatory and the lenders need also to be held responsible for their crimes against the American people.
High interest rates are not the only way that lending can be predatory, but also lending too much. It can lock people into permanent debt, even at "reasonable" interest rates.
Total and complete unregulated markets are almost as wrong as communism. The state has a responsibility to ensure both the freedom of its citizenry to do business and at a minimum some protection against bad actors by hindering their crime.
