@galena I apologize, the last sentence was a bit too snarky. Better version would be
"Consumers show their revealed preferences by being against carbon taxes (which are, like, clearly the right way to price this externality). That likely wouldn't be the case if their contribution was minimal."
@sim @galena
This was the thing I was gesturing at: if consumers have nothing to do with carbon emissions, how come they are hit by carbon taxes?
As for the poor and working class being hit hardest, that seems true, since carbon taxes would probably be proportional to consumption, and richer people probably save/invest more. I consider "there's inequality" a separate problem and to be addressed separately, e.g. by redistribution.
