The brownshirts, for example, were mostly under or unemployed lower class men. And antagonism towards Jews was to some extent based on an envy of an upperclass that included many Jews that had found success in business and industry.
Nazism turned everything upside down. And what some people wanted to believe (that they were superior but unfairly occupying society's lower rungs), political power tried to make a reality through a terrible brutality.
It was all fun and games, for a young Brownshirt in the SA; until the “Night of the Long Knives”.
