Vast and largely unexamined, the world of American charities accounts for fully 10 percent of economic activity in this country, yet operates with little accountability, no real barriers to entry, and a stunning lack of evidence of effectiveness. In With Charity for All, Ken Stern reveals a problem hidden in plain sight and prescribes a whole new way for Americans to make a difference.Each year, two thirds of American households donate to charities, with charitable revenues exceeding one trillion dollars. Yet while the mutual fund industry employs more than 150,000 people to rate and evaluate for-profit companies, nothing remotely comparable exists to monitor the nonprofit world. Instead, each individual is on his or her own, writing checks for a cause and going on faith.
