In the article Butsch explains a lot of interesting things but he also talks about the effects the executives have on these middle class working man sitcoms and how they control what they put out for people to see. My question is, do you think the executives and producers believe that there isn't another story plot that would make money and attract viewers? Cause I could name a few now that have better plots then other older sitcoms. Also, will the sitcom with the middle class dad who is not the brightest bulb of the bunch ever go away?
