I bet if Washington state lowered it's tax rate to equal Nevada's MS would consider relocating MS licensing group back to Washington State...
And then Nevada lowers its tax rate to get it back, and then it's Washington's turn again, the end result being that Microsoft pays a nominal tax if any at all. And since that means other people and companies must pay more to make up the difference, their effective tax rate goes up, they do the same, and ultimately all tax burden gets concentrated on those too poor to move. But of course they can't pay, so the state must cut education, infrastructure maintenance, law enforcement, etc. And that, in turn, makes the state an even less attractive location for business.
It's simply another manifestation of the illness that's killing capitalism. But at least the process of decay is fascinating to watch, as pathological patterns become the norm and eat away the structure of society. Sooner or later it's frayed enough that some crisis launches the final domino effect of collapse.
How about it Washington state, do you want the tax revenues or the talking point against MS?
Washington state wants to survive, just like any living thing. Unfortunately, being a cultural organism rather than biological one limits its options, since it must be careful not to discredit the very mythology that justifies its own existence. And in the US, the mythology of the nation has been tightly coupled with the mythology of capitalism. Untangling them or altering capitalism to less toxic form is a job for the prophetic archetype; Washington state can do little but play for time and hope one appears before it runs out.
Of course, the whole reason prophets are so rare is because you always run the risk of being one of those things found wanting and cast out, but at some point the prevalent mythology of the society has been exhausted of its possibilities so there's little choice except to get a new one or die.
