I'm in my mid 20s. I don't really know any of the ultra-wealthy, but I have some friends who are low execs in IB, Management Consulting, lawyers, have been to virtually every club in the city by now. How to dress when you enter a top club or SoHo House, who to go with, where to go on vacation with what friends to present an image of your wealth, "who did YOU go to the Hamptons with last weekend?" - people present an image to build a network - it's more complex than that, but everything the article is stating is true and may give you an idea.
