It's absurd we remain the only major country on earth not to guarantee health care to all people and paid family and medical leave.

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.

Now all of the ideas that I'm talking about, they are not radical ideas. Making public colleges and universities tuition free, that exists in countries all over the world, used to exist in the United States. Rebuilding our crumbling infrastructure, and creating 13 million jobs by doing away with tax loopholes that large corporations now enjoy by putting their money into the Cayman Islands and other tax havens. That is not a radical idea.

The basic issue of an American society which is fair, which is providing opportunity for all, is nowadays being replaced by the correct perception that we're living in a rigged economy - where it doesn't matter how hard you worked, the result will be all the income goes to the people at the very top. It's leading to a lot of frustration and anger, and people want some fundamental changes to the way we do economics and growth.

If the environment were a bank, it would have been saved by now

I supported Barack Obama originally. I supported him for reelection and the alternative of a Mitt Romney is very, very clear to everybody. And I think the president has done a good job in a number of areas. But one area that has concerned me from day one has been his reliance on Wall Street type people in terms of financial matters.

I think the issue of income and wealth inequality is in fact a moral issue.
