He has leveraged some lovely properties and bought some good deals. He isn't shy about spending money to bring his "vision" to life. In the end, he isn't any more influential than Steve Wynn, another business mogul with cash burning a hole in his pocket to develop over priced venues for the moneyed of the world.
I view golf through this lens. Golf is meant to be played and enjoyed in the outdoors, with views and vistas that take the terrain as it is and viola, a course happens to be there too. They are affordable to many and enjoyed. When the venue is clearly created, when the cost to develop the venue drives exclusivity over enjoyment, then I'm not a big fan. Trump and Wynn like people talking about how exclusive their places are and that's why people should aspire to play there. Because they are "the best." Plenty of fun places that are scenic, fun, sporty, and affordable.
I'll answer this way too. In 100 years no one will be talking about Trump or Wynn. But they will still talk about Ross, Fazio, and Mackenzie.
