All that stuff is great, far better than companies run by finance degree holding businessmen that haven't invented anything in 3 decades and keep existing purely through rent seeking or quarter-to-quarter profit pumping.
To bring Amazon down now, before its had a chance to reap the benefits of its prudence feels like the worst possible signal we could give the market. It'd basically be saying "Don't bother actually focusing on technical improvement, because if you ever do get really big as a result the government will step in and take it away from you".
Though the article does kind of share this sentiment, so kudos to Tom Harford:
>If that is a worrisome state of affairs — and it should be — then Amazon is the shining counterexample. The online retailer’s strategy is driven not by short-term profit but by investment, innovation and growth. If only there were a few more companies like Amazon, capitalism would be in a happier spot.
I suppose the core disagreement then becomes I don't think the threat of Amazon becoming abusive is worth the negative signal going after them would generate, and he does. I'd be interested in reading a 2nd article from him that delves more specifically into this part of the issue.
