This is going to come down to one thing - MONEY! Whatever state/city coughs up the most money will be the "winner." Buying jobs rarely pays off. Boston just "won" the GE headquarters and GE is already announcing layoffs. Personally I'd be wary of a company, that no matter how "successful" it appears by some metrics is not particularly or reliably profitable. Amazon, like most Internet companies continues to be propped up by its stock price. I'll be interested in seeing the effect of the fact it now has to collect tax on sales over a couple years. And it is terribly vulnerable to a run-up in oil prices driving shipping costs up. Plus there is it awful customer service. Its own warehouse deals segment has a customer rating average that would get any other company kicked off its site.
