What has happened to the US is the direct result of unfettered capitalism. The more the wealth gets concentrated into the hands of fewer and fewer people, the more the ultra wealthy need to invest in oppression, surveillance, disinformation and fascism, since a united and well informed public would put their heads on spikes. Other countries are a little better insulated, not having bought so wholeheartedly into the idea of money controlling politics and not having been similarly brainwashed. The USA has been primed to fall first. But the root cause is ludicrous wealth inequality, which is a feature of capitalism and very much a global issue.
