Have you been on an airline recently? Clumsily regulated oligopolies tend to cause races to the bottom in terms of service and hikes to the top in terms of taxes/fees. No, airlines and ecommerce do not share the same destiny. That said: amazon is just another middle man- it's a marketplace with better information/ reliability. extrapolating competition into the future, other equally trusted marketplaces will arise. Amazons benefits of scale are not infinite, and I don't think amazons competitors need to reach her total scale before having similar cost structures. Tl;dr- don't count out competition yet, I doubt ANYTHING on the Internet is "winner take all..forever".
