Hayek had politicans' number:
Rise of the Unscrupulous and the Uninhibited
“Why the Worst Get on Top” is the title of Chapter 10 of The Road to Serfdom (1944), and it lays out the problem. In describing the dilemma of the collectivist who cannot implement his plans without inflating his authority, Hayek’s concern is not with planning so much as with power. He cautions that the supposedly gentle and compassionate morality that induces collectivism does not correspond to the morality of those who run it:
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 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 toward totalitarianism.
