Arab Americans are highly integrated into the U.S. and Canadian economies. Both immigrant and assimilated Arabs are heavily involved in the retail business trade. In many urban areas, they own and manage grocery stores, supermarkets, candy stores, gasoline stations, and restaurants. Some native-born Arabs own small and medium-sized manufacturing and commercial enterprises; most, however, choose careers in the professions (medicine, law, accounting, engineering, teaching). Many unskilled immigrants, particularly recent arrivals, can be found working in factories or restaurants, but they usually remain in such jobs only until they accumulate sufficient means to enter the retail business world. Although Arabs as a group have not faced economic discrimination, individuals have encountered discrimination in hiring and on the job, mostly in the professions.
