This logic seems perverse to me, as one cannot fill a mall with Apple stores, jewelry stores, Ferrari dealerships, and other big-margin, high-density stores -- there simply aren't that many available. Apple stores make vastly more money per square foot than almost any other kind of retailer, and so to use them as a benchmark when they are such an outlier is absurd.
At some point people need a place to go to buy cheap sweaters, inexpensive housewares, and low-cost furniture. If malls don't offer these kinds of places, folks won't go to them, except on the rare occasion when they need to replace their iPhone.
