Terry Gross, Fresh Air, NPR: “In the 1930s, during the Depression, about a million people were forced out of the U.S. across the border into Mexico. It wasn’t called deportation. It was euphemistically referred to as repatriation, returning people to their native country. But about 60 percent of the people in the Mexican repatriation drive were actually U.S. citizens of Mexican descent.
Perhaps the most widely cited book on the subject was “Decade Of Betrayal: Mexican Repatriation In The 1930s.”
Almost as inhumane was “Operation Wetback” in the 1950s.
