What role does Meyer Wolfsheim play in the novel? Why is there so much focus on his nose and what does this tell you about Fitzgerald's politics?

Meyer Wolfsheim is quite possibly Gatsby's mob connection. Apparently he Wolfsheim is the famous guy behind the World Series fix of 1919. His role is to differentiate Gatsby's wealth from the other's in East Egg society. His nose alludes to him being Jewish. If we consider his name and his nose, Fitzgerald is injecting shades of anti-Semitism into his story (Racial slur of Jews being greedy with big noses).
