Vulture capitalism strikes again, exploiting undiversified, banana republic rustbelt towns who misplace their faith in a single, quick-fix, recovery panacea rather than many different industries that are geared to the needs of today.
If you disagree that some rust belt towns are dependent on a single corporation, I think you are either using a different definition of dependent than how I read the original comment use it, or you are not aware that towns where a single factory employs a significant portion of the towns population exist.
The fact that people in these towns can continue to live in them and easily telecommute like any other US citizen or even physically commute to the nearest major US city means that the citizens are not dependent on a single industry.
