Relative deprivation will do the trick. Double the prices of essential goods in the US overnight, and watch how fast a revolt forms, and what violence it will resort to if it meets resistance. Nevermind that everyone here'd still be very well-off by global standards—they'll hang the politician who doesn't give in to their demands, anyway.

Sure, and if a meteor crushes the capitol while Yellowstone violently explodes in apocalyptic volcanic doom all while running out of toilet paper again due to Covid I suspect people will be upset. I don’t envision the hanging of any politicians though.

I think one difference might be that, before now, self-immolation wouldn't have earned any positive attention in the US, while it might have more cultural significance as protest elsewhere. There might have been people in the US who would have self-immolated if they thought it would make a difference.
