Private funding to fight modern day slavery rose by nearly 60 percent over a two-year period but remains too little to make any meaningful impact against the global problem, anti-slavery organizations said on Friday. Between 2012 and 2014, some $233 million of private funds was spent on anti-slavery initiatives - an amount dwarfed by the estimated $150 billion in profits forced labor generates every year, the Freedom Fund and Humanity United said in a report.
