Net Worth: $7 billion
Not everyone can be a technology genius, some are just born that way.

Enterprise is part of the energy market, which is obviously pretty big business. There is nearly 50,000 miles of pipelines with natural gas in the world. Duncan is now one of the many billionaires that didn’t even have to pay an estate tax when he inherited his family’s fortune. Most of us only get a couple hundred bucks in inheritance and still have taxes, but what can you do?
