Social Classes: Shows the differences in the life experience of three male babies from three different social classes. One young man succeeds his father as president of the family manufacturing company. Another, a middle-class white-collar worker at the same company, leaves the town of his birth and moves to New York City where he becomes a respected advertising art director, thus rising in social status. A third, born into the working class, train as a mechanic and holds an influential job at a service station. The sociological tone of the film does not mask a sobering narrative of the limitations that social class divisions inflict on all Americans.
