Narcissism: Why It's So Rampant in Politics
Narcissist politicians don't serve the people; they serve themselves.

Evolution of the Self
Consider that two of the things narcissists most desire are money (i.e., lots of money) and power (the more the better). And these two assets can be tightly interwoven. Consider also that many of the individuals entering the political arena have already made their fortune, or inherited it. So what typically drives them is a lust for power, prestige, status, and authority. These (let's call them) "objects of admiration" not only gratify their need for self-aggrandizement by feeding their oversized ego. They also provide them with compelling evidence to confirm their sense of superiority to others—probably their most coveted need of all.
There's little question that politicians—especially those on the federal level— wield vastly more power and control than the average citizen. Moreover, privy to non-public, industry-related knowledge affords them all sorts of opportunities (blatantly unethical but not yet illegal) to substantially augment their income through "insider" trading and investments. For many of them (and here, as elsewhere, I'll resist the temptation to name names) their appetite for material riches can be insatiable. (And here, see my closely related piece "Greed" The Ultimate Addiction". )
And this boundless appetite helps explain why it's not uncommon for them to leave office with far more wealth than when they entered it. At times the liberty that some of them can't resist taking with the public trust is so flagrant that (moralistically kicking and screaming) they actually end their careers behind bars.
