Yeah, definitely not. It seems like a very high floor, low ceiling proposition. You have to work incredibly, incredibly hard for that salary. I'd say there are other endeavors that are more rewarding, both from a work and compensation perspective. I absolutely adore CFA, but I wouldn't want to manage a fast-food restaurant for six figures.
Unfortunately, I bet you at some point CFA is going to sell to some outside investor, and one of the first things that investor will change is the restrictiveness of their "franchise" model. They'll let just anybody own one, they'll be on every street corner, and the quality of both the food and service will go downhill. Their franchise model is probably 80% of the reason why they are so successful.
