not like there's somebody actively conspiring to alter the structure and vocabulary of English

That's not true at all. Have you never heard of public relations, propaganda, marketing, advertising, and political sophistry?

You have the perspective of society that liberal Americans have, which is all a sort of emotive glittering generalities.

Please, just try reading a few chapters of a popular marketing book. Marketing = actively conspiring to alter the structure and vocabulary of English

Pumpkin Spice... American exceptionalism.... manifest destiny..... insanely great .... hope and change.... service economy..... all bullshit concepts for the consumption of the credulous working-class.

Think it over. No one can know everything, and so we benefit from humility. People can't evolve without humility.
