Why were many jews jobless in 1936?

The reason why there are many jews that are jobless in the year 1963 was mainly because of the reason that they have lost the right to work in specific job categories such as actors, farmers, journalist and even civil servings. Another reason was that they are banned from having to practice medicine and even law as well as operating a business in which led them to be jobless and to have difficulty in earning a source of income.
