Detroit, a once great city, has become an urban vacuum. Its population has fallen to around 700,000 from nearly 1.9 million in 1950. The city is estimated to have more than 70,000 abandoned buildings and 90,000 vacant lots. Meanwhile, desperate Syrians, victims of an unfathomable civil war, are fleeing to neighboring countries, with some 1.8 million in Turkey and 600,000 in Jordan.

Suppose these two social and humanitarian disasters were conjoined to produce something positive.

Gov. Rick Snyder of Michigan, a Republican, has already laid the groundwork. In January 2014 he called for an infusion of 50,000 immigrants as part of a program to revitalize Detroit, and signed an executive order creating the Michigan Office for New Americans.

Syrian refugees would be an ideal community to realize this goal, as Arab-Americans are already a vibrant and successful presence in the Detroit metropolitan area. A 2003 survey by the University of Michigan of 1,016 members of this community (58 percent of whom were Christian, and 42 percent Muslim) found that 19 percent were entrepreneurs and that the median household income was $50,000 to $75,000 per year.

What confidence can we have that traumatized war refugees can be transformed into budding American entrepreneurs? We cannot know for sure. But recent evidence of recaptured children from the clutches of the Lord’s Resistance Army in Uganda and victims of violent crime across five continents reveals that they become more active citizens than similar compatriots who have not suffered from these traumatic events. In the Zaatari Refugee Camp in Jordan, Syrians, despite psychological scars and limited resources, have set up 3,500 shops, stores and other businesses.
