Most franchises appear to be a case of "buying a job".
You pay your $200 - $400K for the franchise
You pay yourself a salary for the 50 hours a week that you work in it.
At the end of the year, is there anything left (Profit after interest & tax)? How much as a % of what you invested?

C'mon - tell us. There must be at least a few franchises that are making their 20% ROI.
