Nobody forced people to go to college and to take out student loans

People willingly took on dept. It is only right, proper for people to pay back their student loans. If people with student loans get a free ride, why not add car loans, credit cards, mortgages, and credit lines to dept forgiveness? How is forgiving student loans fair to people that paid back their student loans, did not go to college, and more broadly, the American taxpayer? Instead of trying to find ways to shirk their legal obligations, people should get on with paying their depts, being the people they committed themselves to being.
