There are four simple answers. Confidence: they don't see role models; they have parents who've said, “You're not going to be an entrepreneur because it's a terrible thing to do” or “I was and it was awful, so I don't want you to do it”. Competence: a lot of kids get through school without any financial literacy skills or other skills that would help them to start businesses. Connections: where do you go, and who's going to help you? Capital: getting the money is a big issue for a lot of people, and it varies so much across the country from place to place.
