Imagine, if you will, an under privileged person of whatever ilk who is honest, willing to show up on time, and do a reasonable job, say flipping burgers. This person wants to succeed in life and is willing to work for it. The manager of the franchise, no doubt frustrated in being unable to find honest folks who show up on time and do a reasonable job, is going to notice him or her fairly quickly. They have then a path to become assistant manager over time, and then manager, they might need to find time to obtain more schooling at night, it's not an easy path by any means. Folks do exist who have done this and who now own several franchises.
It's not impossible. It's not easy.
