Donald Trump and Hayek's Warning

 From The Road to Serfdom, Chapter 10: Why the Worst Get on Top:

It is in connection with the deliberate effort of the skillful demagogue to weld together a closely coherent and homogeneous body of supporters that the third and perhaps most important negative element of selection enters. It seems to be almost a law of human nature that it is 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 the “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. From their point of view it has the great advantage of leaving them greater freedom of action than almost any positive program. The enemy, whether be internal, like the “Jew” or the “kulak,” or external, seems to be an indispensable requisite in the armory of a totalitarian leader. That in Germany it was the Jew who became the enemy until his place was taken by the “plutocracies” was no less a result of the anticapitalist resentment on which the whole movement was based than the selection of the kulak in Russia. In Germany and Austria the Jew had come to be regarded as the representative of capitalism because a traditional dislike of large classes of the population for commercial pursuits had left these more readily accessible to a group that was practically excluded from the more highly esteemed occupations. It is the old story of the alien race’s being admitted only to the less respected trades and then being hated still more for practicing them.
