"I HAVE begun these notes with a note on the big shops because they are things near to us and familiar to us all. I need not dwell on other and still more entertaining claims made for the colossal combination of departments. One of the funniest is the statement that it is convenient to get everything in the same shop. That is to say, it is convenient to walk the length of the street, so long as you walk indoors, or more frequently underground, instead of walking the same distance in the open air from one little shop to another. The truth is that the monopolists' shops are really very convenient--to the monopolist. They have all the advantage of concentrating business as they concentrate wealth, in fewer and fewer of the citizens. Their wealth sometimes permits them to pay tolerable wages; their wealth also permits them to buy up better businesses and advertise worse goods. But that their own goods are better nobody has ever even begun to show; and most of us know any number of concrete cases where they are definitely worse."
