That was a great interview. I wonder if we could engage college grads and college students with tutoring jobs that reduce their student loans at the national level. You could do some amount of tutoring and get a credit reduction. This way you don't have to do a Teach for America type job or work for a nonprofit but maybe get a little help paying things down.
