Try reading the book as a commentary about what the real people at the top do with their lives. They aren't actually helping society, or using their money for good, they are selfish and they suck.

Gatsby comes into great wealth and blows it all trying to attract a girl. Tom Buchanan is a racist and he doesn't want to admit anyone into his class. Daisy literally married just for money and status. Nick is watching them all with disgust and he invites you to join him.
