Saw this happen a few times. One instance was when NCR (National Cash Register) headquartered in Dayton, OH decided to move to Georgia because it had gotten $60M worth (in 2009 dollars) of tax breaks and other incentives there. It followed the incentives sure, so from that point can't blame it, but it had cost Dayton, an already struggling city, even more pain. Another motive behind forced moves is to shed experienced (and thus expensive) / senior people who had been there longer. They are more likely to have families, kids in schools, homes, etc and so might not move.
