Taxes are not a force of nature...

If you were to effectively prohibit all states from giving tax incentives to get companies to make their HQ there, you will fail in 2 important ways. The first one is that there will always be a way to bargain company-state-city wide. So even though the tax burden might be the same, the company could order for , for example,special infrastructure or whatever, to get extra value. And because the city wants to do it, its most likely going to. This result is worse than a tax break.

The other failure will come if you could, somehow, prohibit any thing like the one above from happening. That means that of 2 cities with similar demographics, where one of them has some sort of disadvantage, will be forever barred from having big companies set up shop. Why? Because if there is no tax incentive, the companies will only go to the best option available. If you happen to be that city, you would hit the jackpot. The rest, however...
