In an inversion a company moves its legal headquarters to a lower-tax nation and pays taxes there. It isn't illegal or dishonest or even unpatriotic, it's just good business. Any business that does not take advantage of the opportunity to increase revenue by lowering its taxes isn't being properly managed. The Democrats want to make inversions illegal but that isn't going to work. Whatever laws they pass, with literally billions of dollars at stake, corporations will find methods to get around them. It makes a lot more sense to create an environment that welcomes business.
