>the joke is springfield is a shit town with shit people who sell shit things
Homer is the most notable character in the show which is why they play up his faults to some of the biggest extremes in Springfield. They WANT him to been seen as this super flawed fat, gluttonous, bald, lazy, low IQ retard because he's the face of the show.

This is why he always gets fat jokes and is seen eating out whole buffets even though there's plenty of fatter people in the town who don't get the same mockery for being fat. Krusty has literally the exact same body and even Apu himself gets drawn to be roughly as fat as Homer sometimes. But since Homer is the closest to a main character in a show about flawed characters, the writers go out of their way to make him seem the most flawed of all in many respects.
