The problem was, according to some, was that there were dozens of dealers in every State. In other words, more dealers than could supply all the customers.
For this reason, most legitimate franchisors limit the number of franchises for a given area, lest there be saturation problems.

There is no free lunch. There is no quick and easy path to success. If there was, everyone would be taking it!
