I think we have seen one example of that in terms of one major company moving their headquarters here and that definitely has some positive impact on the job market. But whether or not the tax is the only reason they have done that I can't really say as I don't really know what exactly the reason was they moved their headquarters. One could speculate that taxes would be one factor but whether that's the only factor or not I can't really say.
