A few weeks ago, I attended the premiere of "American Harvest," a new documentary by an independent Rochester, New York, filmmaker. The promotional materials for the film promised viewers an "even-handed," "non-political" look at the agricultural industry in the United States, with an emphasis on the role played by immigration. What we got instead was a naïve, incomplete, and shamefully ignorant portrait of agriculture in the United States-with the same skewed approach to the immigration question that has been all too popular in recent years.
