I am glad you raised this point. Even today in this world of inter connectivity via the web, the cheap international travel, interdependence on trade of oil and cheap Chinese goods, it seems Americans often forget that there is "the rest of the world." Fourteen years ago I transferred from the Boston to London office, and even in the same company Europe was treated almost as an afterthought. Sorry for the negativity because it is an interesting article, but sometimes living over here I am embarrassed to be an American. Lets think globally. It would have been far more interesting to get the global picture of what IT salaries were doing. It would tell the whole story.
