Politically, as a result of Citizens United, billionaires are now able to spend as much money as they want on campaigns, which means that you have a political system which is heavily dominated by corporations and wealthy individuals.

Fifty years ago, great schools like the University of California and the City University of New York - as well as many state colleges - were tuition free. Today college is unaffordable for many working class families. For the sake of our economy and millions of Americans, we must make higher education more affordable.

The truth is that political consciousness in this country is pretty low... To the degree that we can help educate and organize people around the most important issues facing their lives and show that there is support for fundamental changes in the way we do business in the United States of America in terms of income inequality, in terms of low wages, in terms of disastrous trade policies, in terms of being the only major country not to have a national healthcare program - that's success.

I will tell you is the antidote to [Donald] Trump is a very strong progressive agenda that says, yes, I know you`re angry. And you know what? You should be angry because you`re working longer hours for low wages. You have a right to be bitter and you have a right to be that.

Can I work with corporations? Are there good corporations doing incredible cutting edge research and development? Absolutely they are. And we should be proud of them.

I want to know in this day and age, whether it is possible for any candidate who is not a billionaire or who is not beholden to the billionaire class, to be able to run successful campaigns.

In many respects, this country is becoming an oligarchy, with a tiny percentage of America owning the media, owning the country.
