Maybe the United States needs to follow Canada's example and impose a visa requirement on all Mexicans and Central Americans coming to the U.S. No visa, no entry at the border. No visa in hand after you snuck across the border -- well out you go immediately , next plane out. The rules should be very simple. Mexico may whine and cry about this -- but what are they going to do? Impose a visa requirement on the U.S.? Good luck with that! Beyond the drug trade, a growing manufacturing sector (thanks to the U.S.), an overwhelming low wage services sector and a dwindling agricultural sector -- the tourism sector representing 8% of Mexico's GDP is one of the few booming Mexican economic sectors.
