Nope. The reason wealthy people are wealthy is simply because they make a lot more money. I grew up in a wealthy family and I went to a private school where eveybody's parents were wealthy, and I have never dated a guy who wasn't a CEO.

Wealthy people have wealthy marriages, spend massive amount of money on clothing and other luxuries. The reason they have money isn't because they save it. Oh, I'm sure there is lots of money left over. It's simply that they make so much of it.

Ask Jeff Bezos and Bill Gates.
