Apple is only the latest big global American corporation to use foreign tax shelters to avoiding paying its fair share of U.S. taxes. It’s just another form of corporate desertion. Corporations are deserting America by hiding their profits abroad or even shifting their corporate headquarters to another nation because they want lower taxes abroad. And some politicians say the only way to stop these desertions is to reduce corporate tax rates in the United States so they won’t leave. Wrong. If we start trying to match lower corporate tax rates around the world, there’s no end to it.
