In chapter 3 of The Great Gatsby what is being suggested by Gatsby's values?

In this chapter, Jay Gatsby remains fundamentally a mystery. Few of the partygoers have met their host, and Gatsby stands aloof from his own celebration. He does not drink, he does not dance, he remains an observer.He is in stark contrast from the rather putrid group of vacuous people at his parties that speculate on Gatsby himself. Gatsby prefers to remain an enigma. He obviously values the finer things in life but we can question, at this point in the novel, if he values these things for the same reasons others do.
