The consensus has generally tended to be that the modern urban environment offers all the bright lights and benefits of the modern world but often provides working class youths with little in reality. This theory and others were parodied in the musical "West Side Story" (based on Shakespeare's "Romeo and Juliet") in song lyrics such as "Jet Song", "America", and "Gee, Officer Krupke". Moral panics surrounding the advent of teenager subcultures and a perceived rise in adolescent criminality led to several attempts to investigate and legislate youth behavior, such as the Senate Subcommittee on Juvenile Delinquency. One of the many subcultures that was based around street violence was the greaser, a working class subculture that was a part of and influenced the biker subculture.
