Chinese families in the Philippines according to an account I glimpse on TV, they talk about business whenever they meet each other. That's the reason the children learn the ins and outs of a business and they all prosper together.
What makes most children of unschooled entrepreneurs not becoming rich as accounted in the Philippines is that they push their children to become lawyers, doctors, and other high paying jobs. They see in these jobs respect and high status in society. They want to secure their children from the hardship they went through as a struggling businessman. What they don't realize is that they were able to enrich themselves from putting up a business even with a low education. Some would contest that their children could be better entrepreneur as their parents are if they were taught business procedures.
