I know this isn't really a hot take, though. But I don't see a scenario in which we can make real changes that help people, save the planet, and destroy US imperialism without an organized working class - and that requires mass unionization. And right now the deck is stacked so much against unionization, from a legal / policy / regulation standpoint. But also, I do see a whole lot more positive energy regarding unionization among the working class in the US. People really are seeing through the anti-unionization lies spread by neoliberalism over the last few decades. Really, the one big objection from workers is they don't want to get fired, which is totally reasonable. That's why we need to make radical changes to the unionization rules and really beef up enforcement.
And this is has the benefit of being ostensibly in line with the goals of the Democratic party. Now of course, the party is beholden to capital and capital will fight this tooth and nail. But I think there will still be plenty of D politicians who see mass unionization as increasing their base of power, right or wrong.
So I think this should be our electoral focus, even if that means to the exclusion of other policies (because not like we're gonna get shit done in those areas as things stand now, anyway.
While PMC upper management has bought into the system several times over, there's absolutely union potential among the professional grunt workers. Paralegals, nurses, medical resisdents, education workers, social workers. All treated like shit for years just for the chance at entering the PMC class. Telling them their lives can immediately get better would likely produce good results.
