It's almost as if all things Republican politicians say are performance. Like their real goal is naked power at what ever cost. That they will exploit every possible path, I would say that if they though they could do it by being not racist, they would. They have absolutely no principle other than self-enrichment.
Well, it might not be the same rich, but someone will be rich and, by definition, will have the means to live. Your right, but its kind of an always true statement. The wealthy ppl of Rome certainly did not fair well in the collapse of Rome and power moved to new places in that time.
Climate collapse will make it more important to be able to move food around the world. The effect will be to strengthen hierarchies capable of managing global-scale food enterprises. The result will be a hyper-wealthy class that transports food, sustains local farmers via trade, and suppresses them to keep power. Farming will be what everyone does, and it will be essential to keep them doing it as yields will plummet.
This fact is not particularly relevant to the effects of the rise in global temperature.
