Jews are now largely integrated into the U.S. and Canadian economic systems. Although they work in most trades and professions, they are overrepresented (as a percentage of the population) in several, including ownership of small and middle-sized businesses, the communication and entertainment industries, public service, and professions such as Medicine, dentistry, law, accounting, teaching, and scientific Research. Past and present discrimination has been cited by some as the cause of the relatively few Jews found in the upper echelons of the banking industry and large corporations in general. Civil rights legislation of the 1960s and 1970s has outlawed old laws and private covenants that restricted Jewish ownership of land or membership in private associations. The traditional Jewish division of labor with men working outside the home and women working in the home has given way to many women having professional employment.
