It's well produced podcasts done well. If you took This American Life and scaled it to few slightly more targeted podcasts but kept the same quality, that's what they offer. That's less a metaphor than a description of history, given the original founder cut his teeth on TAL and then started Planet Money (also still excellent) before starting his own company.
Okay, that's enough fanboying from me. It's just that I listen to a lot of podcasts, and Gimlet accounts for a large amount of my favorites.
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.
