A national sales tax would have no effect on illegal immigration. It may cut into the amount they send home but will not stop them from coming here. As long as they can make as much or more in one month in the U.S.A. compared to 3-4 months in Mexico or wherever they came from they will still come here. The only ways to stop illegals who are coming here for work is to go after those that employ them. Illegals here for reasons other than work are a whole different story that can't be addressed without closing the borders.AWB

Sure. Some have come here to build a great nation. They think they're George Washington. Unfortunately, they're about 200 years too late.
