Is not the similarity between slavery and mass immigration obvious? (Note to the hysterical that I said “similarity” and not “identicalness.”) They both serve the same fundamental purpose: to provide cheap labor to squeeze working-class citizens and enrich a few.

But what about the third man, William Graham Sumner’s “forgotten man”—the man whose wages are undercut or whose job is entirely lost?
