Well yes, but don't misinterpret the infoprmation - counterfeiters are just as greedy. They're far worse than the companies you criticise, because they (the counterfeiters) are well aware that their fake medicines can kill, yet they greedily go on producing and selling them.
You're sadly mistaken if you think that there would be no fake Gucci bags if the originals were cheaper. Make something that costs £5 and a Chinese counterfeiter will sell copies for £3 - it's the nature of the business. I've seen fake bars of Imperial Leather soap made in China and selling in New York for 30p each.
