I really, really don't understand this focus in the modern service economy. If you look at WV and other midwestern states, labor's power evaporated alongside the decline of the industries where it organized workers. If you look at Canada, their private sector unionization rate has crashed as well, their higher uniionization rates are completely do to public sector unions remaining high.
Unions make sense when you're a skilled trade forming an interest group (doctors, lawyers, sports), have gig work that results in naturally inconsistent work (SGA, WGA, etc.), or are a high-risk occupation that requires a hefty counterweight (mining, construction, etc.) And of course, these aren't mutually exclusive. But for your receptionist, IT guy, customer service reps- I just don't see how service and white collar positions fit into this model or how you'd expand it. I'm all for public safety nets, but Unions aren't really the answer for that?
