I think it's critical that people with degrees & credentials overcome the fear of using "peasant language." The stigma of sounding like you're in touch with your instincts was INVENTED by industrialists, to disconnect "human assets" from natural defenses. No reason to comply.
I meant that people who are in touch with their instincts are much harder to exploit or to deceive, and for that exact reason the ones who control the economy (a generalization) invest into linguistic frameworks that stigmatize "peasant talk."
