The Vandersloots – $3.4B
This family has a long history of bringing family members into businesses. The brother-in-law of Frank Vandersloot was the founder of Oil of Melaleuca. The company used to sell tea tree oil, but it did not prove to be successful. They also got in trouble with the FDA thanks to accusations that they inflated medical stats to make their product seem better. He eventually rebooted it to sell cleaning supplies, nutritional supplements, and homecare products. It did way better than the first time around!
