I’m assuming that statistic is based on the Forbes article. But it’s misleading. It describes a billionaire as self-made if they didn’t inherit the family business. So Bill Gates, for example, is a self-made man because his father was a lawyer and his grandfather was a bank president and Gates made his fortune in software. But Gates grew up in a family that was able to send him to a private school where he had access to computers back in 1970 and then pay his tuition to Harvard.
I don’t know about you but I wasn’t raised in that kind of wealth and luxury.
