In an interview with Trump published in Forbes Oct. 10, the article's author alluded to the president's lengthy history and fixation with the list. According to the publication, the bulk of Trump's fortune is "tied up in a half-dozen buildings in and around midtown Manhattan in New York City, where luxury real estate values have fallen recently".
Declines in real estate prices, the settlement of the fraud lawsuit against Trump University and declining numbers of visitors at some of his golf resorts all contributed to the drop-off, the magazine said. "A record 169 billionaires did not make the cut this year, falling short of the $2 billion minimum needed to make the list", the report says.
