Question

Where does Tom believe Gatsby’s fortune came from? What evidence from earlier chapters might corroborate the belief that Gatsby’s business dealings are not totally on the level? From the Great Gatsby.

Answer 1

The most prevelant rumor is that Gatsby got his money through bootlegging (illegal sale of alcohol), which he did through his ties to the mob. Daisy tells Tom at one point, that Gatsby owned a chain of drug stores, and that is how he got rich.
