For years, the media has been printing propaganda by farmers and growers warning about a veritable food Armageddon if they don't get all the cheap labor they want. The articles are just a scare tactic used because growers want a cheap, pliable labor force rather than employing legal workers at a good wage under good conditions. The self-styled reporters who write these articles invariably fail to ask growers any questions that might reveal that they're just engaging in scare tactics.

By 1999, it took only 5,000 workers to operate machinery that harvested some 12 million tons.
