An inflow into the urban core of Detroit creates promise and tension: lessons for Birmingham?

Futurist Richard Florida, writing for Atlantic Cities, flagged a  provocative piece in the Detroit News, written by Karen Dumas, former press secretary for Detroit Mayor Dave Bing.
The piece discusses the fact that young, predominately white urbanites are flowing into center-city Detroit, a trend seen in metros around the country including Atlanta. That's beginning to happen in Birmingham too.
While that inflow can be positive for the economy and may start to reverse decades of population decline, it often leads to tension between the new arrivals and the long-suffering Detroit natives who didn't or couldn't move out.
