“In the Public Interest” is an organization dedicated to warning the public about the dangers of privatizing public services.
It has written a guidebook to explain to citizens what Social Impact Bonds are, how they work, who they benefit, and why they are dangerous for our society.
Shar Habibi, ITPI’s director of research, writes:
“Our guide is a must-read for any citizen or decision-maker trying to understand these new financing structures. It will help you ask tough questions to ensure that private dollars don’t create perverse incentives, fail to serve the neediest cases (also known as ‘creaming’), or distort measures of success for our most important social services.
“Ultimately, Pay for Success ignores the deeper cause of many of our growing social problems: underinvestment in the public interest. America desperately needs more investment in all our public services. Prevention-focused public funding of critical public services—like pre-K for all children and help for juveniles who end up in the criminal justice system—is our simplest and least expensive solution.”

Very informative guide, with pertinent questions we should not only ask, but demand some answers to. So disheartening to see the profitization of social services designed for the public good. Thank you for sharing this.
On a day when Koch bros are meeting with US prison department, this is particularly poignant! It is amazing to me that these guys (1%ers) get away with the blatant disregard for humanity under the cloak of doing good! David Koch gives money to “public” media and no one bats an eye. They buy the prison system and have the gall to pretend they will fix it! They’re the ones who want to fill the prisons (3 strikes)and feed grown men for 2 cents per day to make money off of misery. It is all connected, we have youths in the “justice” system stuck in solitary confinement. My good friend always says,”follow the money”! Sometimes it’s hard to see, but this is in mainstream daily news!
