In the 1930s, during the Great Depression, the United States deported large numbers of recent Mexican immigrants so that American citizens could take over the agricultural jobs.  Then during World War II, with most of our male work force abroad in uniform, we needed them as workers again, and started the Bracero Program.  In the modern day, we are a little split personality on this issue, where we enjoy the benefits of their labor – cheap food and products, their spending in our economy, paying taxes for Social Security they will never get back, etc., at the same time as some want all undocumented workers deported.  We want our cake and eat it too.
