Take it away, Don Brownstein: "Before Copernicus, there was the view that earth stood still and the sun moved around it. That was the view that told basically that the universe was static. That's turned out not to be true. I think people who believe that policy is somehow or other exogenous to the behavior of fixed-income markets are just deluded. The Copernican Revolution took place a long time ago in physics and it's about time that something like that took place in finance."
