If nothing keeps everyone together, how can there be a revolution, how can they put the differences aside and unite against the government and political elites? On the contrary, pushing people against each other is how people are kept from revolting. Plus throwing everyone in prison for the smallest things (especially those likely to unite against the government), making people very afraid of the police, controlling narratives in mass media and media platforms, etc. I'd say US is one of the few countries where power is not just really well protected, but that protection is future proof. Look how all the new ways of spreading information, new media platforms ended up in the hands of few big domestic corporations who are obviously big supporters of the system they exists in and are very cozy with the government, with spreading propaganda, with censorship of pretty much whatever the government asks to the point of censoring literally all views on certain subjects if they do not parrot official government propaganda.
