Mexico was a top ten economy on the world stage before the Second Great Depression. Mexico and America worked together to fight the drug cartels along a border over three thousand kilometers long. The Great Depression hurt everybody. America’s central government collapsed, and the Mexican government didn’t fare much better. But what few people north of the old border know is that the Mexicans and Americans worked together to end the threat of the drug cartels forever. And then they agreed to come together and form a single union. America did not take over Mexico as many people think. It was a merger of two powerful nations into one superpower.
