Why were wealthy people attracted to fascism in the early to mid 20th century?”
… and socialism was being widely spread and adopted throughout Europe in the early 20th century. But that is a very simplistic answer. You need to understand what fascism was/is, and the personalities of rich people, probably each one as an individual. I suggest you read here http://www.abelard.org/briefings/fascism-is-socialism.php and some of the linked pages. Also http://www.abelard.org/henry-ford.php, which includes data on Ford’s relationship with A. Hitler.
