Hot take but I think it’s because people stop having or seeking out novel experiences. Most of people’s lives are repetitive and boring jobs with barely any time to zone out in the evening. And once your kids move out and you’re with a long term partner, hardly anything is dynamic in your life. Or fresh. Or unexpected.
I’m highly skeptical of the impact this would have, I don’t think the US would feel it much at all. Those isolated places are about it but that probably wouldn’t last long and I doubt US leadership cares much.
