It's a useless way to frame the issue. Environmentalism is an easy sell. It's much easier to get people to agree with socialism if you use climate change as part of your argument. But framing climate change as "first world vs third world" is just about the dumbest thing you can do because it puts everyone in the first world on the side of the corporations who are actively trying to downplay and obscure climate change.
If you make an actual, internationalist appeal for fighting climate change then you will have no problem getting people on your side. But framing the issue as "this one group of people is hogging all the resources and we need to stop them" will inevitably play into the hands of ecofascist rhetoric that views humanity as a virus on the earth.
Sorry for venting. Feel free to dunk on me in the comments
I'm not saying that the contradiction between first world and third world workers should be ignored. I'm saying that the contradiction can and should be resolved without the destruction/negation of one of those groups. That's what I mean when I say the contradiction isn't antagonistic the same way as the contradiction between labor and capital or between the proletariat and the bourgeoisie.
I would generally agree with that, with some caveats, at last synthesis has been achieved
This is the power of the dialectic comrade :hammerandsickle:
