It's the 11th largest because drugs are probably the largest industry in the world. If you believe otherwise you are just fooling yourself and Palin's got a bridge for you to buy.
Are you aware of all the manufacturing in Mexico? For example, most of the engines in American cars are built in Mexico, especially around Saltillo. Are you aware that Walmart, Sam's Club, Home Depot, McDonald's, and many more American franchises are all over Mexico now? Do drug cartels invest in business to launder their money? Sure, especially in the state of Sinaloa. But before judging the whole country keep in mind it's the American users primarily that finance the cartels. It's not the average Mexican that benefits from the cartels but the corrupt politicians and law enforcement that do. Most Mexicans are no more involved in cartel profits than the average Express employee in FedEx profits. And in all honesty, you sound like the xenophobic, jingoistic yahoo you claim the folks at Fox News are.
