The Simpsons were developed as the caricature of the American Suburban Nuclear family. They literally have 2.5 kids, cat, dog. Homer works at the Nuclear Plant. Now, it has been a long time since the late 80s, and the Simpsons have drifted so far from it's original intent that it's not even the same show. Sort of reverse South Park, where it got better as it distanced itself from its original intent.
I mean, it's probably getting better then it has been, but it will never be what it was, as that lightning has been let out of that broken bottle long ago.
