Breaking news: in one of the most productive countries / economies in the entire history of humanity, the majority of people creating that productivity do not get to enjoy the rewards of that productivity.
Honestly I think people are just tired of being stuck between a rock and a hard place of literal authoritarianism and apathetic stagnation. Even if one is clearly better people are desperate for change and the best leader that we have to look up to is a stuttering old man who complained he wasn't paid enough while being extremely upperclass and having a stay at home nanny for his kids.
People crave representation and I can see why they complain about the extreme lack of it. And lashing out at the downtrodden do not get them to feel better. You can't whip a smile onto someone's face.
