Deceive the rich and powerful if you will, but don't insult them.
If you once forfeit the confidence of your fellow citizens, you can never regain their respect and esteem. You may fool all of the people some of the time; you can even fool some of the people all the time; but you can't fool all of the people all of the time.
Oh, what a tangled web we weave, when first we practice to deceive.
The easiest person to deceive is one's own self.
You can fool all the people all the time if the advertising budget is big enough.
