(Chapter 9) Who attended Gatsby's funeral? How and why is this significant?

The only people who come to Gatsby's funeral are Nick, the minister, Henry Gatz (Gatsby's father), four or five servants, the West Egg postman, and Owl Eyes. Considering the thousands of people that attended his parties, this turnout says a lot about the superficiality of East Egg society. It is also ironic that Gatsby's muse and obsession, Daisy, did not attend. Gatsby had everything yet had nothing.
