The world isn't going to die overnight, it's going to happen slowly, and it's already started. Failed crops, mass migration, water shortages, etc. The rich need to maintain the ability to influence policies like immigration to stretch out their miserable existance.
It doesn't seem to occur to them that they'll be killed and eaten by their own security guards, once the collapse of civilization renders their money moot.
At this point I think there might just be an element of pure reaction and contrarianism involved. Dying's worth it as long as you own the commie nazi libs or whatever
Yeah I'm seeing this at the level of my provincial government (Alberta) all green energy projects being indefinitely canceled/ not being approved in favor of oil and gas based power. Ostensibly to protect jobs but the rhetoric used about it clearly just being backlash against the commie libs (and Turdeau of course)
