So let me end by addressing the elephant in the room here, which is the seeming inability to get anything done in Washington these days. I realize we are not going to resolve all of our political debates over the best ways to reduce inequality and increase upward mobility this year, or next year, or in the next five years. But it is important that we have a serious debate about these issues. For the longer that current trends are allowed to continue, the more it will feed the cynicism and fear that many Americans are feeling right now -- that they'll never be able to repay the debt they took on to go to college, they'll never be able to save enough to retire, they'll never see their own children land a good job that supports a family.
