B&B was created by Mike Judge, who also gave us Idiocracy, which shows us pretty clearly where his head was at in both cases. The point of the show was partly stoner humor sandwiched in between video music segments on the then-new MTV channel. It's not exactly high art, but it is quite obviously intended as satire by the creator of the show. The intended audience point of view is not that of B&B, who are deliberately presented in such extreme absurdity in order to be unrelatable. The viewer is expected to see B&B the way the straight-man(ish) characters of the show do, as tiresome unfunny nuisances or worse, lacking any sense of self-awareness. Although it could be seen as being sympathetic to the characters themselves, especially given the much greater amount of screen time they get, this may have been simply necessary in order to secure protracted attention from the large fraction of juvenile manchildren in the original MTV audience, whom the show had to ensure it didn't turn off even as it was trolling them specifically.

I think especially since idiocracy came out, it's evident that B&B was in part a crude attempt at social engineering, a gentle way to grant the sort of people who might find themselves symathizing with the main characters the crucial power those characters lacked, which was to see themselves from the outside. It's fair to say that if this is true, it hardly moved the needle in that respect, and may even have slightly backfired.
