No pill can heal that wound. Imagine you're a Government worker with 15y of experience. You would automagically think about the public as "them". If you're an Admin or IT-Guy, you "already" do that, by separating you from the "Common User".
And guess what, there is nothing wrong with this. It doesn't produce bad habits or bad intentions, because this is totally dependant on the persons character.
That sounds like it would increase the us-vs-them rhetoric, not decrease it.
