The best solution to the illegal alien problem from Mexico is to make Mexico the 51st state of the United States.
Since the Spanish-American war, or the battle at Alamo in which Texas lost but nobody seems to remember that part of the story, Americans and Mexicans have flowed back and forth across the southern border of the United States – or perhaps it should be stated as the northern most border of Mexico.
The southern states in particular, California, Arizona, Texas and the southeastern states have prospered due to the cheap labor provided by Mexicans, who work as migrants or laborers in the United States, but do not have the benefit of insurances, the right to vote, or to enlist in the army and fight in Iraq.
