Social Justice - Alan Khazei and Vanessa Kirsch

"Social entrepreneurs will lead change as politicians led change in the 1960s," Kirsch says. "But it's a different kind of revolution. It's not a revolt in the streets; it's institution building. But we don't have a system to take any of those innovations to scale -- yet. While we have social innovation that we believe in, and that has been proven, there's no system to take that innovation to scale. That's the next battleground."

That vision thing.

"America is in a transition period now," Khazei says. "Don't forget, for 50 years, when we were in the middle of the Cold War, it was very clear what our mission as a society was. And it was also very clear what the role of government was. Then the Cold War ended, and we didn't have an offensive mission. What are we trying to accomplish as a country? We have no idea. And the irony is that we sit atop the world. America is like a colossus: We have the resources to do so much. We just need to find the will."
