However politicians know it is easy to vilify corporations thereby allowing them to either out right lie about how taxation works or lie by omission.
Companies moving their head quarters out of your country should be a clear signal that your doing it wrong, except in the case of the US politicians want to punish them for doing what is right for them, their share holders, and their employees.
The power tripping in Washington is so extreme that punishing is their first reaction to anything they don't like.
