This is not an April Fool's joke. This is reality. From the article:
"Even as immigration soared in the 1990s, crime rates in the United States began to tumble. The vast majority of the 11m Mexicans there are “hard workers, risk-takers and savers”, as a diplomat puts it. The border has never been more secure; net migration from Mexico is now negative, taking into account 100,000 deportations last year (which the Obama administration carried out with Mexico’s co-operation). American demand for drugs is literally killing Mexicans, with 60,000 dead in the country’s drug war. When Mr Trump points to Mexico’s $58 billion trade surplus, he fails to note that every dollar of goods it sends across the border contains 40 cents of Made in America content."
