Thanks to the War on Drugs.
REFERENCE: The Mérida Initiative (also called Plan Mexico by critics) is a so-called "security cooperation agreement" between the United States and the government of Mexico and the countries of Central America, with the declared aim of combating the threats of drug trafficking, transnational organized crime and money laundering. The assistance includes training, equipment and intelligence.
In seeking partnership with the United States, Mexican officials point out that the illicit drug trade is a shared problem in need of a shared solution, and remark that most of the financing for the Mexican traffickers comes from American drug consumers. U.S. law enforcement officials estimate that US$12 to 15 billion per year flows from the United States to the Mexican traffickers, and that is just in cash, i.e., not including the money sent by wire transfers.
The U.S. Congress passed legislation in late June 2008 to provide Mexico with $400 million and Central American countries with $65 million that year for the Mérida Initiative. The Merida Initiative was announced on 22 October 2007 and signed into law on June 30, 2008.
Yep. Instead of blaming their own ridiculous policies from welfare, gun control and the WOD, they blame a guy who’s just a friendly south of the border narco-trafficker.
