@toomuchtodo: no, at scale, they don't. And in tech, a country has very little to offer unless it possesses something you can't get elsewhere, which the USA doesn't.

Why do you think there is so much 'business' going on between larger enterprises and government at many levels? It's all to keep them around, not because it's the best fit. Take Amazon, they want to build an office, so all states and counties and whatever else you have in local government bends over backwards to try and reel them in.
