There are two usages to the word "vanity." The one you're referring to has more to do with dignity (the desire to be respected by everybody.)
The property under scrutiny by the parent poster, though, is (I think) more like "narcissism"—the desire to be perceived as the best person ever by as many people as possible.
The desire for dignity is universal; whereas narcissism is a (rather uncommon) personality flaw.
