It's the consumer that drives China to clone - they would not bother if there was not a ready market
Well, that really depends on the situation. Sometimes a fair amount of blame falls on the manufacturer, especially on those 'high end' list items which The Cromwell just mentioned. If the manufacturer does not make enough items to meet demand, either because they lack the capital or they are trying to keep the price high by keeping it exclusive, the manufacturer holds some of the blame as well. Not to mention customers might have to jump through hoops to even get a chance at the item (like joining a group, downloading an app, etc)
I don't support the idea of clones nor do I buy them, but all the blame doesn't fall on the customer in every situation.
