>>104224602because she is part of the FOX-cartoon-sitcom-family anti-patriarchy archetypal marriage, in which the patriarch is a symbol of unfitness and the matriarch a symbol of fitness.
the father is a fat clown whose only positive contribution to the family is their assumed wage from an explicitly meaningless job (or no clear job at all), who is otherwise exclusively repressive (often quite brutally) to his family-subordinates. his bumbling incompetence and stupidity (advancing to literal and explicit mental retardation, in many cases) provide to core of the works comedy.
the mother in contrast is almost never the butt of any jokes (or, if she is, the joke is to be based on her excess of positive traits including traditionally masculine ones), physically fit, is the true head of the household, openly regards the father as another charge to be cared for (only humoring any sense of authority).
nearly all domestic/family-themed sitcoms, especially cartoons and especially the FOX line of family-sitcom cartoons, are expressions of this archetype. the glaring exception being KOTH, which was a sincere parody of the American family as it was, rather than an attempt to influence how it would be.
