That's mischaracterizing the situation. They're not unprofitable because they're charging less than they could, they're unprofitable because they pour their profits immediately back into growing other business avenues. If Amazon spent a quarter or two slowing/halting the development of new business ventures they'd immediately be profitable. If they spent a year doing that and also trimming prior unsuccessful ventures they'd be quite profitable.
