The expected argument is probably something like “it's economy of scale”, but in practice it absolutely looks the other way round: Amazon is much less profitable than it is more expensive than the alternatives[1], so if anything their seems to be negative economies of scales. [1] if you're twice as expensive than a company that has say 10% margin, then with equal costs you should be with a 55% margin. And Amazon is more often than not more than twice as expensive as the alternatives.
