An expense for businesses and households that can afford it (and they'll surely write it off their taxes), is not equivalent to the impact on poor people who will be put on the street if they aren't already homeless. It's delusional to think that we'll make any impact on climate change by asking the poor and young to sacrifice what little quality of life they have left. In the end, people are going to vote for their best interests. Rich people that benefit from polluting and exploiting the environment and the poor/young have aligned incentives. Any climate change solution that doesn't include lifting up the poor and helping the young and disenfranchised is a waste of time.
