What I loved about this series is that it was different from other sitcoms of the '50's. In other words, it was not set in the middle-class white bread suburbs. Most of the action took place in the Kramden's tenement apartment in Bensonhurst. And both Ralph and Ed were blue-collar workers who struggled to maintain a decent standard of living.
Of course, if this series was made today, Alice and Trixie would also be working outside the home, but in low-paying, menial jobs, such as waitresses or file clerks.
