This is why I have a big problem with metric called "productivity". Same service done in New York by the same worker is worth X times more than in a small town. Hence people who move their shop suddenly become 10 times more productive, even if they're doing the same thing exactly as efficiently as before. Then people look at the graphs and say "no wonder these poor places are undeveloped - look how low their productivity is". It should just be called labor cost and not productivity.
