A job should lift workers out of poverty, not keep them in it.

I do believe that we should substantially lower student debt in this country, which is crushing millions of people. We pay for it, in my view, by a tax on Wall Street speculation. The middle class bailed out Wall Street in their time of need. Now, it is Wall Street's time to help the middle class.
