Friedrich Hayek explains why statist party leaders and ideological foot soldiers find vilification so important to their program:
“It is in connection with the deliberate effort of the skilful demagogue to weld together a closely coherent and homogeneous body of supporters that the third and perhaps most important element of [leftist cohort formation] enters. It seems to be almost a law of human nature that is it easier for people to agree on a negative program — on the hatred of an enemy, on the envy of those better off — than on any positive task. The contrast between “we” and the “they,’ the common fight against those outside the group, seems to be an essential ingredient in any creed which will solidly knit together a group for common action. It is consequently always employed by those who seek, not merely support of a policy, but the unreserved allegiance of huge masses.”
— F. A. Hayek, The Road to Serfdom, p. 139. Read the chapter from which this is taken, “Why the Worst Get to the Top”, for the context in which these remarks are made.
In 2009 one of the objects of hate is Friedrich Hayek himself — identified as an object of vilification by Australian Prime Minister Kevin Rudd and ideological foot soldier Naomi Klein, among many others.
