mark0's argument would make a lot more sense if there was evidence that college educated professionals were the ones fleeing. in fact, the opposite appears to be true. Chicago's population is holding relatively steady at a time when poorer neighborhood populations are dropping. Those who leave the state because they don't like taxes, retired people who leave for better weather (and lower taxes) and poor people fleeing Chicago due to crime - these aren't typically sources of innovation. Meanwhile, I believe UIC enrollment is at an all time high, and I'm not exactly hearing about problems at U of Chicago or Northwestern. I'm not selling my stock in Chicago any time soon.
