2017’s Richest Person and How They Made Their Money: REVEALED!

7. TIE: Charles Koch, 81 – Net Worth: $47.9 billion

Next up on the list and tied for 7th place are the infamous Koch brothers. Chairman, CEO and one half of Koch Industries, Charles Koch oversees more than 120,000 people and more than $100 billion in annual revenues from their various companies. Koch Industries is invested in spaces including petrochemicals, electronics, cattle ranches and raw materials.

The Koch brothers have always been steeped in controversy, unlike many other members of this list. One of their biggest investments is in petrochemicals, and when you couple this with their huge involvement in politics, it is hard to ignore a potential underlying agenda. It was also revealed recently that Charles had been planning to reshape American politics for over 40 years, and he also has a long history of funding political campaigns throughout US presidential campaigns.
