WARREN: I grew up in a family hanging on by our fingertips to a place in the middle class. But back then, America invested in kids like me. We had a lot of opportunities. Today, Washington lets big corporations like GE pay nothing -- zero -- in taxes while kids are left drowning in debt to get an education. This isn't about economics -- it's about our values. I'm Elizabeth Warren, and I approve this message because Washington has to get its priorities straight.
