Postmodernism's foundation is distrust of power and authority as corrupting and highly dangerous, and to be prevented and opposed at all times (not just postmodernism - look at the US Constitution, for example) - power is an evil in itself (like the Ring). Postmodernism was inherently democratic, opposing the centralization of power and built, it seems, on the foundation of 'all are created equal' - liberté, égalité, fraternité.
As so many have followed the conservative reactionary program of discarding and scorning postmodernism - try talking about equality or human rights or humanitarianism and see what the response is - now people suddenly find no obstacle to authoritarianism, and even if they distrust it, they've disarmed themselves unilaterally by abandoning postmodernism's defenses.
So we see this power-worshipping (not power-skeptical), authoritarian (not democratic), hierarchical (not egalitarian), contempt for others culture taking over everywhere: politics, government, business, social relations, ... why not? I even see it in family, tragically.
In fairness, that's an expansive definition of postmodernism. There's not enough time or space here to be more precise, sorry.
