F. A. Hayek observed that the bulk of supporters of fascism and National Socialism prior to World War II did not come from the poor or rich classes. Rather, he notes:
"The resentment of the lower middle class, from which fascism and National Socialism recruited so large a proportion of their supporters, was intensified by the fact that their education and training had in many instances made them aspire to directing positions and that they regarded themselves as entitled to be members of the directing class."

Sounds like some of the contemporary political movements in both parties in the United States today.
