An idea for a GOOD federal law

"No state or municipal government shall hand out direct payments or special tax breaks to a private entity for the purpose of encouraging it to move headquarters or operations to that goverment juridiction from a different juridiction with in the United States."

This would be a good use of the interstate commerce clause for a change. This law would prevent states from trying to lure companies away from each other, which leads to companies playing states and cities against each other. Its a zero game between state and local governments that only large corporations win.
