The American prison system is massive. So massive that its estimated turnover of $74 billion eclipses the GDP of 133 nations. What is perhaps most unsettling about this fun fact is that it is the American taxpayer who foots the bill, and is increasingly padding the pockets of publicly traded corporations like Corrections Corporation of America and GEO Group. Combined both companies generated over $2.53 billion in revenue in 2012, and represent more than half of the private prison business. So what exactly makes the business of incarcerating Americans so lucrative? http://xrepublic.tv/node/3882
