Wrong.
The Vanderbilts were one of the wealthiest families in the 1800s and 1900s. Up there with the Carnegies, Rockerfellers, Astors, etc. They had wealth. And now, almost all the wealth is gone because the kids were dummies. It’s a common problem. The first generation makes the money. The second generation grows the money. The third and fourth generation blow the money.
Doesn’t negate my point that wealth doesn’t die in one or even a couple of generations. It’s not about networth, it’s about the longevity of the money.
