You've got a point, but most people (even those with jobs and a high school education) are not educated to be owners. At best, most people are taught to go to school, get a job, and live paycheck to paycheck, paying their rent and bills.
Education of the people has to start somewhere. I can tell you that many people grow up thinking they are supposed to be born, live, and die in poverty. Anytime they get something that is beyond that, they feel that they are beating the system. Most people who are able to evolve out of that state of mind end up leaving. Which is why you don't hear about many success stories out of the hood.
