In one era the United States did two things to people of Mexican descent: it imported Mexican men by the hundreds of thousands under the Bracero Program as temporary hands on contracts often broken, and in June 1943 it let servicemen beat and strip Mexican American youths in Los Angeles for wearing zoot suits while police arrested the victims. Together they show a welcome extended to labor and refused to workers.
For many participants the Bracero Program was a chosen economic opportunity as well as a system of exploitation. Death tolls from the riots are uncertain, and the violence was initiated by servicemen and civilians, not the youths blamed at the time.
