If all your friends thought cannibalism was cool, so long as you didn't eat each other, you would either have to be a cannibal in the first place or hadn't realized it when you found these friends and decided, to fit in, you would become one--after all, nobody else seems to mind, and your friends are so powerful and prestigious, so why should you care?  Now, replace cannibalism with psychopathy, and it's not hard to see how it's possible that so many politicians tend to be one way; lying to get their way without any regard for other human lives--except their friends, either within the click or in business, sometimes both (as is the case of the Monsanto corporation, off the top of my head.)  If you received huge piles of cash to keep the circus going, why would you stop?  For good conscious?  If your business thrived through manipulation of politicians, why would you stop?  Because it's "wrong"?  The benefit severely outweighs morality; as the saying goes, "Power corrupts.  Absolute power corrupts absolutely."

I'm still waiting for an explanation as to how government and businesses can exist in one room without circle jerking--and furthermore, why no one in support of these two coexisting can stop it from happening, since it has been happening for as long as the two have existed throughout history and still is at this very moment.
