I'm as good as you

You can get him to practise, not only without shame but with a positive glow of self-approval, conduct which, if undefended by the magic word, would be universally derided.

The feeling I mean is of course that which prompts a man to say I’m as good as you.

The first and most obvious advantage is that you thus induce him to enthrone at the centre of his life a good, solid, resounding lie. I don’t mean merely that his statement is false in fact, that he is no more equal to everyone he meets in kindness, honesty, and good sense than in height or waist measurement. I mean that he does not believe it himself. No man who says I’m as good as you believes it. He would not say it if he did. The St. Bernard never says it to the toy dog, nor the scholar to the dunce, nor the employable to the bum, nor the pretty woman to the plain. The claim to equality, outside the strictly political field, is made only by those who feel themselves to be in some way inferior. What it expresses is precisely the itching, smarting, writhing awareness of an inferiority which the patient refuses to accept.

And therefore resents. Yes, and therefore resents every kind of superiority in others; denigrates it; wishes its annihilation. Presently he suspects every mere difference of being a claim to superiority. No one must be different from himself in voice, clothes, manners, recreations, choice of food: “Here is someone who speaks English rather more clearly and euphoniously than I — it must be a vile, upstage, la-di-da affectation. Here’s a fellow who says he doesn’t like hot dogs — thinks himself too good for them, no doubt. Here’s a man who hasn’t turned on the jukebox — he’s one of those goddamn highbrows and is doing it to show off. If they were honest-to-God all-right Joes they’d be like me. They’ve no business to be different. It’s undemocratic.”

-- CS Lewis, "Screwtape Proposes a Toast" published Dec 19, 1959 in the Saturday Evening Post

In the time since that was written "Superiority" and "Inferiority" has moved further from a statement of usefulness to reading as a statement of subjugation -- as if to underline the message given by Screwtape all the more.
