This is what oligarchy looks like: Today, the top one-tenth of 1 percent owns almost as much wealth as the bottom 90 percent. The top one-hundredth of 1 percent makes more than 40 percent of all campaign contributions. The billionaire class owns the political system and reaps the benefits from it.

It reminds me in some ways of the debate taking place in this country and around the world in the late 1930s. There were people, in this Congress, in the British Parliament saying, 'Don't worry! Hitler's not real! It'll disappear'.

We can combat climate change effectively. What we are lacking now is not the brain power, not the knowledge, not the technology. What we are lacking is the political will power, and we need your help by the millions to tell Congress to stop worrying about their fossil fuel contributors to their campaigns and worry about their kids and grandchildren.

No. It is not acceptable that the 6 largest financial institutions in this country have assets of almost 10 trillion dollars, and issue half of the mortgages and two-thirds of the credit cards. That is too much wealth and power in the hands of a few. If Teddy Roosevelt were alive today he'd tell us to 'break them up.' And he'd be right. These huge banks must be broken up.

As a result of the digital age and the decline of first-class mail, there is no question that the Postal Service must change and develop a new business model.

I have taken on virtually every element of the big money establishment, whether it's the Koch brothers, and the big energy companies, whether it's the industrial complex, whether it's Wall Street... I have taken on the drug companies. I have taken on the insurance companies.

We can have paid family and medical leave. We can make public colleges and universities tuition-free. These are not revolutionary, radical ideas. They're kind of common sense.
