It's a third- world environment, but with unions and Democrat labor laws.
Normally I wouldn't entertain the idea of politicizing what is clearly an economic and social development issue; but what the hell I'll respond.
I'm not sure how you think that unions work where you are from. But here in the US what they do is monopolize the labor pool for a given trade on a per entity basis; they do not annex an entire cities population all at one a time. But, solely for the sake of your argument, let's say that a labor union somehow actually DID manage to maintain the peoples faith, in a swing state that has been losing jobs and economically depressed for the passed four decades, and which also currently has a Republican Governor, enough so that they still have some semblance of a presence. And just to get it out of the way let's assume that this union also specialized in shale oil extraction, something that Ohio has never exported on any kind of a scale before. That union is only going to concern itself with it's niche in the host entity. Where as the over whelming majority of jobs and wealth being created are going to be from externalities that are not directly associated with this market. Now if you are contending that the unions are the reason that the jobs left this area in the first place then you are making the mistake of assuming that any of the host entities production models stood a snowballs chance in hell of competing with or catering too emerging markets. They didn't, not a single one of them even tried.
