Why is meyer wolfsheim a one dimensional potrayal in the great gatsby? why does Nick do this?

Wolfsheim is an archetype that Fitzgerald uses to illustrate Gatsby's character as well as the era. A notorious underworld figure, Wolfsheim is a business associate of Gatsby. He is deeply involved in organized crime, and even claims credit for fixing the 1919 World Series. His character, like Fitzgerald's view of the Roaring Twenties as a whole, is a curious mix of barbarism and refinement (his cuff links are made from human molars).
