Well for McD's it's getting into management and going to McD school and then getting a franchise. McD's likes to promote from within. There are quite a few millionaires who have done this. I mean I am sure you have to work hard to do this and it isn't guaranteed either. I think a lot of franchised businesses can work this way.
I personally know of a husband and wife who own 8 franchises in a region and were able to send their children to the best schools in the world. High school education for the parents. They did exactly what you said.
