What has happened on the national level is that individual states don't have the same competitive advantage over other states that they once had. Back in the post-WW2 period manufacturing jobs moved from older U.S. cities (primarily in the Northeast) to other parts of the U.S. (mainly the Midwest and South) to take advantage of lower labor costs, lower utility costs, etc. Now that we have insisted on "nationalizing" more and more laws and regulations that affect these factors (i.e., employers have to pay SS and Medicare payroll taxes regardless of where they do business, they have to comply with OSHA regulations no matter where they do business, they have to buy electricity from utilities governed by FERC, etc.), these places don't have the same cost advantage over the major U.S. consumer markets that they once had.
I don't have a problem with businesses that relocate out of my state. If my state is going to be stupid enough to over-regulate, it's going to lose business. It should.
