One caveat: Bezos is the richest out of people that we can get an accurate and publicly available estimate of their wealth. It doesn't count people like Vladimir Putin because we don't actually know how much he's worth- but many suspect that it could be more than 100 billion. It also doesn't count families, such as the House of Saud, which has several members worth over 10 billion, and the entire family might be worth over a trillion. http://fortune.com/2017/07/29/vladimir-putin-russia-jeff-bezos-bill-gates-worlds-richest-man/ http://fortune.com/2017/07/29/vladimir-putin-russia-jeff-bez... https://en.wikipedia.org/wiki/House_of_Saud https://en.wikipedia.org/wiki/House_of_Saud
