You never hear little kids say they want to be "powerful" when they grow up. Parents don't encourage that sort of thing, since it's kind of terrifying coming from a toddler.
Yet, power is what everything else on this list is about. Fame is about having power in the relationship with the fans. Beauty is about gaining power through others' sexual desire and jealousy. Genius means society needs your skills more than you need its approval. Money . . . well, money and power are conjoined twins.
So it's pretty safe to say that while not many of you reading this specifically aspire to go into any kind of political office, a great many of you do aspire to some kind of power. Maybe you're eying the kind of job where you'll be the boss, or maybe you want to go into law enforcement. Or maybe you're just driven by that bitter, unspoken urge almost all of us feel at least once in our youth: "I'll show them! I'll show them all."
So What's the Problem?
Saying "power corrupts" is stating something so obvious we feel stupid even typing it. It's like saying elevators elevate. If you found out tomorrow your congressman was caught firing orphans out of a cannon, you'd barely raise an eyebrow.
It has nothing to do with the "culture of corruption in Washington DC" the Libertarians are always talking about. You find it everywhere, from the asshole supervisor to the bitter gym coach. Small people driven to mindless, unethical behavior, drunk on just a few drops of bullshit power. They often can't make friends, their marriages end badly, they self destruct. The world is full of these miniature, sad Tony Montanas, destined for a proverbial bloody downfall.
Usually instead of a mansion it's a cubicle, and instead of bullets it's a series of pissy emails
Wait, it gets worse...
The thing is, it's the desire itself that's poisonous. You find that need for power most in the type of person who hates having to obey all of society's social contracts, particularly the ones that require them to not act like cocks all day. These are the people who are only nice guys because of fear of retribution if they do otherwise, so their main goal is to become strong enough that no retribution is possible (this is why sociopaths tend to seek positions of power, by the way).
So it's not just that power will destroy you. It's that the urge itself is bad news. That desire for power is a vicious, ravenous animal and feeding it only makes it strong enough to tear its way out of your belly and go on a bloody rampage.
