Willy Foote of Root Capital provides his thoughts on Goldman Sachs' involvement in the U.S. pay-for-success scheme.

From original article: "Kudos to Goldman Sachs for taking a step into the nascent impact investing market—whether for PR reasons, or genuine concern, or a little of both. More and more investors crave these new opportunities to put their private capital to good social use. Let's hope more Wall Street leaders put skin in the game."
