> There's a cocktail party version of the efficient markets hypothesis I frequently hear that's basically, "markets enforce efficiency, so it's not possible that a company can have some major inefficiency and survive".

The hypothesis is that the market (not products as you assume) are efficient, leading to the optimization of share prices to reflect reality.
