That’s in no way a rich people thing. Polluting less often means that stuff people are used to will cost more or will be less available.
The greens in Germany suggested that maybe meat is too cheap and people should eat it less and maybe also don’t drive your car so much. And a good chunk of the population lost their fucking mind at the audacity to suggest doing something in two sectors that massively contribute to climate change.
The reality is that effective action against climate change is hugely unpopular and politicians realize that it’s often political suicide because people hate change and there is no way to combat climate change without lifestyle changes for every single citizen.
