It doesn't have to be said. If there is an experiment to prove the cheaper drug A is just as good at treating a sickness than the more expensive drug B, then what do the results say? Would people still want to buy the more expensive drug? The experiment speaks for itself.
If I had an Audi and a souped-up Dodge Spirit and they somehow hit the streets just the same, and I went around showing how it was so...then surely people would ask me why I still owned the Audi.
Do people still want to buy diamonds when cubic zirconia is available? Just sayin'
or are they both viable options aimed at differnt segments of the market?
