What hope do we have for self governance when the poster child of bad economic regulations, universally derided for having the opposite effect for which it intends, can still be implemented? Are governments incapable of learning? Are we doomed never to make any political progress on policies that are counter-intuitive, even when there is overwhelming agreement and empirical evidence of its harm? This makes me cynical of climate change. Even if we do achieve a carbon-neutral lifestyle, who's to say the next generation of politicians won't make the same arguments being made today against stopping climate change?
