Is labor organizing in the imperial core regressive?

My simplest kick back would be "what other options are there to somewhat improve things?".

Even if all organising labor in the imperial core achieved was giving workers better access to tasty treats (and that really isn't the limits of what it achieves) - That's still deconstructing the power imbalance and giving workers more of a say, politically and economically, and less resources left for bourgeois imperialism and propagandism. That's good progress.

The reality is that workers in the imperial core really aren't doing well, and to call them 'labor aristocrats' is a bit wild to me. Many are in povertous, sub-human conditions. They're mostly eating edible-foodlike-products that aren't food, they're increasingly dosed on medicines to make them better proles, they're having all the mental will to live sapped out of them at every turn, and are increasingly compelled to spend every waking hour (and sleeping hour honestly) working or in other form of service to the capitalist class. Even the goal of most treat consumption is to give any leftover money back to the bourgeois class, instead of actually being a pleasant time or connecting with peers.

Organised labor does more than "me have stuff", I would argue half the point is to build new systems that give people communal alternatives to the capitalist's insisted way of life.

So yes, I'd argue organising labour is a very obviously and powerful force for good anywhere. But even if you didn't accept that, there is no alternative. Other than to sit there and let the bourgeois class have full control - And you truly are confused if you think that is anything but the literal worst option.
