Statistics on the scale of this issue are becoming as well known as they are shocking. Estimates put the number of modern slavery victims at almost 50 million globally – including those in forced labour or living in forced marriages. Of these, 17.3 million are being forced to work by private businesses, with nearly 4 million in forced labour imposed by state authorities. More than 3.3 million of those in forced labour are children.
Damn, the US has 5% of the global slave population.
Prisons?
Yep, all prisoners in the US can be and usually are forced to work for private companies upon threat of torture.
