No one is truly self-made but this excludes the people that got their wealth, job, or a $100,000+ loan to start their business from their super rich dad or family.
By know I mean people that you have actually met and had a conversation with. Not the richest person "you know of." (Ex. Mark Zuckerberg)
How much is their wealth? 1,000,000? 10,000,000? 100,000,000?
