Bill Moyers, in a preview of Friday's show, released a clip of an interview with founder of the Farm Labor Organizing Committee Baldemar Velásquez.

Velásquez, a 1989 MacArthur fellow, talked about the ongoing David vs. Goliath struggle most farm workers face when the system is largely run by corporation. "I told the Campbell's Soup executive, I've told the Heinz executives, I've told the Dean Foods executives, I told the Mount Olive executive CEO and I'm telling Reynolds America right now: You're a good man, but the system you operate is wrong and is built on inequity."

Watch the preview, posted on on July 18.
