That’s the natural progression of a young political unit (which the US is): As the intelligentsia become more and more dominant, patriotism is decried as inappropriate nationalism or outright racism, causing such dramatic splintering among the voting populace that the political unit never again acts or reacts uniformly or consistently. The head of the state, as it were, decapitates itself and neutralizes its own political power. China is all over this and doing everything it can, starting with Nixon in the 1970s, to bring the US down from within using this technique, all the while enforcing compliance with Communist policies among its own populace and strengthening itself from within.
