The cartoons were made in mid-centry 1900s, and the characters either portray nuisances to agricultural life, military symbolism, crooks, and those related to small town life. Each cartoon is a melodrama about such life then, especially in times of strict Christianity. Chip n Dale are meant to be dicks, as they symbolize teenagers fucking with the adults
... and not all of the adults are really that swell either. Mickey Mouse is really the only shining hale on these cartoons, except that he comes off as annoyingly fake, which is always symbolic in a small town setting. Donald is less than angelic. He is often portrayed as the dick that pretends to be the shining apple with ill-intent.
