Nearly half of America's farm workers are undocumented migrants. If they were all deported US agribusiness would collapse.
The big business of farming in the US is booming but undocumented migrants are ripe for exploitation. NAFTA has forced Mexican farmers out of business by allowing the US government to use taxpayer dollars to heavily subsidize US agribusiness and export cheaper produce to Mexico creating an uneven playing field where Mexican farmers can't compete.
