Even climate change as a problem is largely driven by the oligarch class. The working class would have been alright driving the smaller cars used to drive in the 2010s, and would have likely been okay climate action even in the late 80s. Especially since the cost would have been much lower if action was taken at that time.
That is if the oligarch class did not wage relentless propaganda on climate change science and any solutions, instead promoting the fossil fuels industry which they own.
