Maybe to a degree but it's people that Lear that actually tried to be thought provoking while being humorous as well. The world could use more Norman Lears and Susan Harris' IMO. Both of them were able to bring some critical issues to the table while still putting out funny television.
As for Lear, it's not like he hasn't tried to bring an AITF type of thing on TV after the fact. In the '90s he tried with 704 Hauser in 1994 which was set in the Bunker house with a black family. They basically tried to recapture the Archie Bunker model but flipping it with John Amos playing the patriarch of a black working class democratic family with a conservative son and his white, jewish girlfriend. I remember show being even MORE political than AITF but it didn't pan out.
