The bar is set pretty low regarding what we expect from CNN at this point, but even by their Wolf Blitzery standards this "Voices from the Rust Belt" thing is delusional. It's little more than a variant on the Hard Working Americans / Salt of the Earth Blue Collar Types (read: white people who live in shitty places) theme that the mainstream media simply can't let go, probably on account of the fact that their average viewer is 65 and thus able to remember a time when Erie, PA mattered.
Having ruminated over the causes and consequences for decades, the present reality is that there is no real economic reason for these places to exist anymore. They once serviced geographically-bound industries that either have ceased to be relevant or have been brutalized by free trade agreements. As I tell every single half-sentient adult I meet in rural Central Illinois, the solution to the problem is to leave. Get out. Move somewhere with jobs and something to do. The good times are never coming back to Buffalo and Flint.
As the CNN piece itself notes, most mobile individuals do leave, and in fact have already left. So, one might ask their producers, what is the point of focusing on these places? Why do we care about the Voices of the people left behind, the vast majority of whom are just too old to let go of the place psychologically. Anything that could be done to "save" these places is never going to be done; the country is too all-in on globalization and the inerrant wisdom of the free market to countenance sentimental arguments about saving some massively polluted shit hole in rural Ohio.
They can call it whatever they want, but we can spot "Let's tell our old, sad, white viewers in Scranton or some other place we wouldn't live on a bet that they're still really important" when we see it.
