What you earn depends on what you learn.

We are very frustrated because we have a Supreme Court that seems determined to say that the wealthier have more right to free speech than the rest of us. For example, they say you couldn't stop me from spending all the money I've saved over the last five years on Hillary's campaign if I wanted to, even though it would clearly violate the spirit of campaign finance reform.

The most important question of the 21st century is not what or how much, it is 'How?' How do you propose to turn your good ideas into positive changes in other people's lives? You must be the 'how generation.'

If you wanted to create jobs in a way that has minimal effect on the deficit but has government action, the two best things you could do are the infrastructure bank and a simple SBA-like loan guarantee for all building retrofits, where the contractor or the energy-service company guarantees the savings.

You could create a million jobs doing that.
