The Walton Family
Sam Walton in 1962 decided to start a small mom and pop store in Rogers, Arkansas. Today that shop has turned into the gigantic retail chain Walmart. According to Forbes, seven heirs now own more than 50 percent of the company’s stock with a value of roughly $247 billion net. Walmart consistently dominates the market and is one of the top revenue earners in the US. In 2016, the company brought in the largest revenue of the year – $482 billion.
