Well many wanted to buy cheaper and cheaper
Well, I don't think that's how it works. Consumers didn't drive the market towards cheaper prices. Companies, and in particular large companies, pushed for lower production costs. The fact it benefited consumers (well, at least partially - price-wise, sure, but quality-wise, that's another story) is, IMHO, a side-effect. Given the cost difference between producing in western countries and eastern ones, companies could get higher margins while offering lower end prices for their customers, further increasing demand.
Of course, once customers are used to low prices, they won't go back to higher prices. Unless there is no choice anymore.
So, just saying that the idea that commerce is only, or at least mainly, driven by demand is an utopia that just doesn't meet reality. That's what marketing is all about. And these days, what you, as a customer, can buy at a given price is completely out of your control. Ultimately, shareholders get to decide.
So, while I agree that customers are also responsible for the situation - not buying the cheap stuff would indeed stop the process, - they didn't create it. Just a thought.
