Many citizens used to buy cheap goods in order to save some money, but they don't do it twice, because they'll have to buy again because of the bad quality. Moreover, it has been discovered that the deaths of many people was due to the ineffectiveness of fake medicines. Counterfeiting is a real obstacle to creativity and development.
