1. Legalize, then regulate the illegal drugs coming across the border and turn the cartels into legitimate business men, who pay taxes.

2. Make it easier for Mexicns to become citizens legally or obtain a work visa so they can pay taxes and get health insurance.

3. Run two waist high fences paralel across the entire border. Place them 40 feet apart. Every 1/4 mile place a sign with a picture of a dismembered body. Fly predator drones non stop inbetween these fences and drop bunker busters on anything that has a pulse.

4. Offer work visas to any illegal immigrant currently in the country who can proove employment. Then deport the rest of the basterds.

The $$$ mexico looses by illegal migrants wire transfers will be more than made up for by the tax revenue generated by trade and redially available work visas.
