Austerity is all the rage in Washington these days. See President Obama's State of the Union address and the GOP's response. Seemed like a good time to chat with Brown University political science professor Mark Blyth, who suggests the austerity push is not as virtuous as it may sound. So I've got a Q&A with him in this week's Phoenix. But he probably says it best in this nifty video, produced in the fall.
