This is why most of the West is doomed. Why the hell would anyone start up a business in California if they pull stunts like this? Indeed, if you've got an online business with no geographical boundaries, why even host it in the US/Europe? Why not host it in a country that actually -wants- productive citizens?
In economic terms, a tax is basically a government's way of saying, "we don't want you to do that". An income tax is basically saying, we don't want you to work. A payroll tax is basically saying, we don't want you to hire people, etc.
Stuff like this will only hasten the demise of the US.
