Obviously Microsoft changed Seattle but to imply that Amazon did not contribute to significant economic growth is silly. Amazon would have a cascading affect on so many industries in Denver Metro that would benefit the whole economy. On the downside housing would get even more expensive in Colorado so the state really needs to cut down on regulation to reduce housing development expenses and identify a way of importing foreign construction workers. And BTW corporate welfare in the form of taxpayer money is the new normal, its an unfortunate cost of attracting business these days.
