Can Arab-Americans Save Detroit?

Bobby Ghosh reports on the influx of Middle Easterners to the Motor City:

The four-county region of southeastern Michigan has a population of at least 200,000 of Middle Eastern origin; some estimates put that number far higher. ... For Detroit, a city in critical condition, this new blood could make a difference. The impact is twofold: a desperately needed infusion of new citizens at a time when an exodus has drained metro Detroit of its middle class, both white and black; and an economic boost from a culture that likes to start new businesses. The Arab-American community in metro Detroit produces as much as $7.7 billion annually in salaries and earnings, according to a 2007 Wayne State University study. (That amounts to more than twice Detroit's annual budget.)
