Gatsby has done everything he can to complete his American Dream. Gatsby is wealthy, has many material possessions and has a large house. The only thing that Gatsby is missing is a wife to start a family with, and he moved into West Egg just to be near Daisy so he can complete the dream. He has hosted parties in hopes of seeing her there and developed a plan involving Nick inviting daisy to tea so that Gatsby can see her. Gatsby has put his full effort into completing the American Dream, and that is what makes him "purely American".
