I would much rather continued US world domination than cede that power to China. Yes, that's easy for me to say as an American, but I can't help but think that other Western nations would suffer as well under China's dominance.

Yes, the US's liberal democracy isn't in the best of shape (to put it mildly), but China is an isolationist, authoritarian nation where state censorship and human-rights abuses are the norm, not the exception.
