Period. It's a waste of time. Any government that tries to force standard of living reduction will be voted out of office. This is essentially what happened with Obama, and he tried to do it in a stealthy way. Imagine someone openly taking an axe to public prosperity in the interest of climate change? They'd shove knives up his ass like Quaddafi.
You have to create a totalitarian state with the full apparatus of secret police, surveillance, detention camps and summary executions to even start to go there, and the focus on climate change would impair your ability to maintain that social control. Beside which, the inherent corruption in such a state would ultimately subvert your efforts to reduce your carbon footprint.
Also, i'd rather have the climate change than the secret police, thanks.
