The video presents a talk show conversation with the authors of a book called “White Cargo” (2008). The thesis of the book holds that the indentured servitude used to provide labor to the American colonies was, for the most part, a white slave trade.
The indentures (contracts) were often involuntary and a large part of the traffic consisted of kidnapping Irish and British children and collecting convicts from prison for export to North American plantations. The authors argue that slavery in the Colonies began and persisted for many decades as the slavery of whites; in fact that colonial black slavery evolved from this origin.
White Cargo itself is available as an audio book (11 hours), here:
