the whole "why should we do anything to mitigate our climate effects when billionaires exist" drives me up the wall. Changing societal attitudes matters. It's the difference between, say, a local city council allowing mixed-use buildings vs not. Also, if you want to play the "there are people doing worse than me" game, maybe look at most of the fucking planet. The average USian uses *far* more resources than the average global denizen. No excuses.
