The Middle Class Sitcom

Last class we discussed the idea that many sitcoms or generally funny television shows are typically based around a middle-class-like family. Many families on these shows like Family Guy or the Simpsons would not be in that middle-class range because the wives do not work and the husbands are idiots who work seemingly low-paying jobs. However, they all seem to be doing alright financially. Sure, they may bring up money on an episode or two, but it isn't the central focus of these shows.
Personally, I feel that looking at sitcoms/cartoons from an economical and class standpoint is pointless. It's a sitcom. It's mean't to be funny. Sure, some shows may have a sappy point to make about morality at the end of the episode, but for the most part it is events played out in a comedic way by actors or cartoons. Why should we divest time into thinking about how much money each person in these families makes? It really doesn't matter. They are fictional characters. If someone wants to bring up that they're not representing certain people appropriately, like lower classes, think about this: I'm sure someone could make a funny show about a financially struggling family, but it really wouldn't be funny. We'd keep being constantly reminded about their struggle and hard times. That's depressing. Sure dark comedies work, ABC wouldn't buy that show for primetime.
