Probably my failure to properly attribute the 27 million figure to your book Disposable People was due to my own inadequate reading of the iAbolish site. A search of the site following your correction of my attribution yields this:

Using a simple but strict definition of slavery – forced labor for no pay under the threat of violence – sociologist Dr. Kevin Bales estimates that 27 million people live as slaves worldwide. In his groundbreaking new book Disposable People: New Slavery in the Global Economy, Bales advances the thesis that much of contemporary slavery has become a quasi-industrialized institution: a brutal but efficient and profitable process of entrapment, exploitation, and abandonment. Slaves are lured or abducted from their homes, psychologically and physically intimidated, forced to work in de-humanizing conditions, and then discarded when they are too ill to work.

I look forward to reading Ending Slavery: How We Free Today’s Slaves.

Minimizing labor costs on infrastructure projects, mining, and agriculture in the third world seems to be a driver for enslavement. I wonder how we can shine the light of public scrutiny on international corporations that use slaves (to build pipelines, for example), and on the private security companies that enforce enslavement? Perhaps you have already covered this in one of your books.

The good news is that we can bring slavery to an end in our lifetime – my new book, Ending Slavery: How We Free Today’s Slaves, gives a solid plan involving governments, communities, the UN, relief organizations, and each one of us, to eradicate slavery forever. The book’s available on Amazon, our website, and just about everywhere else.
Many thanks
Kevin Bales
