So, to understand what's being said: People make money off the
  backs of slaves. Private slavery ended in the 13th Amendment.
  Government slavery began in the 13th Amendment. The form of
  slavery is the Prison system of the USA. So, slavery continues
  to be primarily minority, although just as there were white
  slaves in the past, there are still white slaves today,
  explaining the presence of white slaves in the form of
  prisoners. The premise is that money is being made off the backs
  of the prison slaves. My only question is this: What work are
  these slaves doing? I can definitely go with the argument that
  the exception clause in the 13th Amendment created the
  conditions for transferal of slaves from private to government
  ownership - at the time. But today? I don't know. Perhaps I'd
  have to read the book but it's not really my thing. I _can_
  however, see a good portion of his argument and I find it
  agreeable. Just, not all of it. And* ? The migration of people
  from socialist --> capitalist USA is not a counter argument for
  it assumes foreknowledge of the potential to become government
  slaves. Just as the concept of
  Prison-as-institutionalized-slavery is new to me, I well imagine
  it would also be a surprise to anybody who is migrating here. ==
  I had to really think about it. I've heard that "prison is
  institutionalized slavery" before yet I thought it had to do
  with the number of minorities incarcerated. But I never knew of
  the connection to the 13th amendment exception. That blew my
  mind. ==
