The biggest thing that I believe has doomed all countries holding on of their norms is social medias ability to make everything a conspiracy and make people feel like they are playing an "ARG". Just look at this DOGE stuff, its the bedrock of the whole administration. They are simply (illegally no doubt) firing people and cutting programs on an industrial scale. But how is this presented to the public and through the administration?
It's presented through social media posts, which are written as if they "hacking the government" and "finding corruption". They aren't, they are just cutting things and then lying and claiming there is X/Y/Z conspiracy behind it. But by posting it on social media, and people get to interact directly with these people, they believe they are actually part of the "game". When you combine social media, conspiracy theories, gamify the interactions and glorify anti-intellectualism, this is the result. The insitutions and norms crumble because they are not built for the second "printing press" and exploited by those seeking to do the most harm.
