Breaks in the Chain: What Immigrant Workers Can Teach America about Democracy is a new book by Paul Apostolidis about the social activism of Mexican immigrants.  He teaches at Whitman College and with his students has been helping to organize Washington State farm  workers.   More about this here.   The Old Mole's Laurie Mercier talks with him about how the health of citizens (through the food we consume) rests on the physical and mental suffering of immigrant workers, and on what these workers are doing about it.
