Re: profiting from consumer inertia
No, effective monopoly (either literal or just collusion among the few players to offer the same terms) is THE cornerstone of business in general - actual competition is well and truly dead, buried, rotted to dust and long forgotten in practically all but a very select few markets - essentially, everywhere where barriers to entry could be erected to any sort of meaningful height, which is almost everywhere. When the overwhelming majority of customers shop in supermarkets, you can't even "compete" on stupid-basic stuff like fruits or vegetables - you sell to a store chain for whatever it is they are offering (and kiss their feet for the privilege...) or don't sell at all. Everything else is much worse.
