Fear and egoism is probably causing the rise of the far-right, fear of not having enough, and egoism of "Why do I have to share?" (and being dumb enough to believe "make it great again" lies). And then the idiotic "center" who doesn't want to lose voters start moving to the right. With the decaying planet less capable of producing food, there'll be less, and there'll be more of that scarcity mindset (although do we even have scarcity, maybe it's just the uneven distribution, with billionaires eating cows that's been fed grass that's grown with the purest glacier water flown by helicopter from the Swiss alps...).

In one aspect, the autocratic rule of Xi Jinping has a positive: "We're going to cover the whole mountain with solar panels, and force electrification of cars." and there's no busybodies protesting and threatening to vote his party out of office.
