"Try a little research, junior."
Forbes compiles a list of the richest Americans. Only a handful of them were born rich. Unless you're coming from a position where, if you're born in America, you're born rich. That's a valid point...if that's a point you were trying to make.
Furthermore, it's pretty well documented that even the wealthiest familes see their wealth decline as the amount of wealth is not able to grow fast enough to support a family that is expanding at an exponential rate. The Vanderbilts, for instance, didn't have a single millionaire in the family by 1973.
I'm going to give you the same advice I give my subordinates. If you don't know what you're talking about, then don't talk.
Sometimes it's best to not talk...allow yourself to preserve a little credibility.
