I found this old film through James Howard Kunstler's website. The words to the film were apparently written by Lewis Mumford. The first few minutes showing farm life aren't that interesting, but the scenes of the city and the actual living conditions of a city which appears to be Pittsburgh are fascinating, as are the huge traffic jams filmed in the 1930s. These are a pretty interesting demonstration of the way people saw the problem of the American city in the early 20th century.

Clip 3, cities going crazy, traffic jams and crowds:
Part 4, the planned alternative, the suburbs (with magically no cars):
