“Just as the democratic statesman who sets out to plan economic life will soon be confronted with the alternative of either assuming dictatorial powers or abandoning his plans, so the [aspiring] totalitarian dictator would soon have to choose between disregard of ordinary morals and failure. It is for this reason that the unscrupulous and uninhibited are likely to be more successful in a society tending towards totalitarianism.”
–F.A. Hayek, The Road to Serfdom
In other words, those who are willing to compromise their morals are much more easily promoted in governmental (and corporate) bureaucracies.
