Then Hitler somehow convinced the center right President to grant him powers

Class interests are how. Hitler came to power by promising big business interests that he would crush labor unions and socialists and promote the interests of capitalists, which he largely did. The term "privatization" was first used to describe the Nazi economy. Many of these rich Nazi collaborators survived and thrived under the Nazis (so long as they weren't part of a minority), and also survived its fall. The company that manufactured Zyklon B, for example, eventually became part of the company now known as Bayer. The rich accepted fascism as a calculated risk because the country was in crisis and there was a risk of communists coming to power and redistributing their wealth.
