Since 1925 the Streit’s matzo factory has sat in a low-slung tenement building on Manhattan’s Lower East Side. While other matzo companies have modernized, Streit’s remained a piece of living history, churning out 40 percent of the nation’s unleavened bread on pre-War machinery as old as the factory itself. In a neighborhood where the Jewish immigrants long ago moved on, in a nation where progress and profits trump all else, where manufacturing has left the cities if not the country, where family businesses are bought out by giant corporations and workers move from job to low paying job, filmmaker Michael Levine captures the Streit’s saga and echos the American Dream.
