Even if they had their own flaws, Lisa and Marge being morally superior to Homer and Bart is a long-running premise of the show.

> morally superior

I'd say, totally superior, this was in 2000:

"Lisa has become the (first female) President of the United States and tries to get the country out of financial trouble."

And I don't consider that "morality" was the major aspect of Lisa's superiority.

Bart becomes chief justice of the Supreme Court in the episode "Itchy & Scratchy: The Movie".

I guess so? Marge and Lisa both have major ticks/obsessions that kick in, just like the other two.

When the plot is about Home and Bart, the other two play counterpoint. But the opposite is true. Homer just ends up getting the main role so often that we assume that to be the default state of the universe.
