The Duncan Family (Net Worth: $26 billion, Company Name: Enterprise Products Partner)
The Duncan family is a stellar example of living the American Dream. Dan Duncan was raised by his grandmother in rural Texas, and he grew up in a poor family. As he entered into adulthood, he decided to try his hand in the oil industry, and as luck would have it, he struck big.
The company now pulls in billions of dollars annually. Dan Duncan passed away in 2010 but his family has taken over the business and have proven themselves to be adept at it too. He left an estate worth $10 billion to his children, and they have since managed to more than double the amount.
