I agree, but right now the externalities are also supported by the better-off, as they can also get cancer and what have you from dirtier air, that’s one of the prime reasons for this push. In the new regime almost all the weight falls on the less-off.

Almost all the cancer falls on the poor, not just because they tend to live closer to power plants (unlike carbon dioxide, CFCs, and even sulfur dioxide, the pollution that causes cancer is fairly localized) and work in coal mines, but because there are more of them.
