As I see it, 80% of people are basically decent; their basic instincts are to live by the Boy Scout virtues. 20% of people, however, are what you might call potential trouble sources, inclined toward doing the wrong thing when the opportunity presents itself. They might now be shoe clerks, mailmen or waitresses–they seem perfectly benign in normal times. They play baseball on weekends and pet the family dog. However, given the chance, they will sign up for the Gestapo, the Stasi, the KGB, the TSA, Homeland Security or whatever. Many are well intentioned but likely to favor force as the solution to any problem. But it doesn’t end there, because 20% of that 20% are really bad actors. They are drawn to government and other positions where they can work their will on other people and, because they’re enthusiastic about government, they rise to leadership positions. They remake the culture of the organizations they run in their own image. Gradually, non-sociopaths can no longer stand being there. They leave. Soon the whole barrel is full of bad apples. That’s what’s happening today in the US.
