We live in an environment of planned obsolescence and mindless consumerism. A high quality of life can be achieved for everyone globally if we wanted to do so. Instead we sustain a system designed to extract 'profit' as it's driving virtue.
Wait until you see what ecofascism really looks like as we wring the last bits of juice out of the planet.
Yeah, it's the imperial states doing the vast majority of the extraction, but here is the thing, people in exploited states almost universally want to live more like people in wealthy nations, and people in wealthy nations don't want to live like people in exploited states. I've never heard a solution to that problem that isn't just another form of ecofascism.
A culture that non-coercively encourages people to have one less kid than they otherwise would is the only path I see that doesn't ultimately depend on autocracy.
