Archie Bunker, as played by the very liberal actor Carrol O’Connor was the butt of every joke and perpetrator of every evil deed on the show was in fact a lower middle class blue collar union worker. The only member of a household of four who worked. He alone supported a stay at home wife, a married daughter, an unemployed son-in-law who was in college studying to be government employee and later a grandson. And Archie was the bad guy?!
That point was actually articulated on the show to refute the son in law’s condescending attitude towards Archie.
Do you remember the spin-off, "Gloria?"
The daughter works for a Veterinarian played by Burgess Merideth. The story line picks up after she and Meat-Head had lived in a commune for several years. Meat-Head abandoned her and their son, Joey. She leaves the commune and is hired by the pet clinic while she attends school to become a Veterinarian.
Just when you thought Meat-Head couldn't be less contemptable!
