The 1890s were the launching point for widespread unionization among coal miners in places like my home-state of Kentucky. Company towns were increasingly common, and major motivations for unionization were to combat things like being paid in company skrip or letting neighborhood kids ("breaker boys" as young as 8) work in the mines. Their social lives--from their neighborhood, to their social "clubs", to the literal currency they were able to use--were entirely defined by their job and the company they worked for.

Tough to use them as proof that this "doesn't have anything to do with economics" when their entire social life was defined by the economics of coal mining.
