i am not entirely convinced by the daily beast arguments... but more fundamentally, what Costco says is that they find it profitable to increase teh wages that they pay above the norm, so that they can retain workers and focus on their productivity withut as much turnover. That is inherently not a model that can be expanded to the economy at large, if EVERYBODY raises wages, then you are no longer paying above the norm, and are no lonoger getting the turnover stability that Jalinek says is so important to the cosco model.
