The middle class in America is at a tipping point. It will not last another generation if we don't boldly change course now.

It means joining with allies to deploy renewable energy technologies -- both at home and around the world -- to confront the very real and present danger of potentially irreversible climate change.

The message is resonating, not just in Wisconsin, but all over America, the people are sick and tired of establishment politics, establishment economics. They want real change.

The point is change can come about, but it only comes about when millions of people are actively involved in political struggle, the billionaires may have the money, but we have the people.
