No. 171 on the small cities list, just two from the bottom, Flint seems to make more and more of what Americans don’t want. In 2006, it made more than 170,000 pickup trucks; it’s doubtful it will see that level of production for a long time to come. And this is a place that was hurting even before gas prices went up. More than 40 percent of all manufacturing jobs disappeared between 2002 and 2007.
