Just to point out something that people often forget. While not condoning slavery in any form myslef (just to be clear). There are issues where slavery exists in the third world in which the slave is supported by the slave owner, often the owners supply the slaves with land to work. Once they have been freed normally under western NGO pressure to the government they kick the former slaves off the land they own and so while technically freer they have no money, no land and no hope of working. I noticed in the parts of the article quoted there was no mention of money to help set up the freed slaves in their own businesses or money for land redistribution either.
What I am trying to say is that people often talk about freeing slaves as though that is the end of it but normally that is only the first step because without financial help and general support you will find the situation where the freed slaves will try and sell themselves back to their former owners.
Just food for thought.
