We do not need to have isolated areas open to bid of money to politicians to create them. We need one sells tax as the only tax with none other. We could raise imports by the level of difference in cost of living between nations. So isolated tax free zones like Libya or Venezuela don't get more trade. If we must have an IRS cut them to 5% across the board. But the sales tax would be paid by the rich and the illegal aliens alike. Once paid the working class could grow from their labors and not just support global bankers.
