Reality is reality. Nobody is going to beggar themselves voluntarily and no politician is going to get elected on a platform of forcing them into penury.
It seems to me that there’s a gap between what technology can currently deliver and what people would like to happen when they fly to G7 meetings and Davos junkets in their private jets to decide what will happen to their charges.
Is there any actual evidence that spending money on CC will force governments into penury? In my view, it doesn't much matter what money is spent on, it will go round and round and stimulate the economy. For example, armaments aren't productive, yet large amounts are spent on them without governments going broke.
