The Greenlining Institute goes where the money is. Last month’s Foundation Watch described its role in promoting a philanthropy disclosure bill that prompted large private foundations in California to promise more grants for minority group nonprofits. A master at shaking down deep-pocketed institutions, Greenlining ordinarily takes on banks and other financial institutions, pushing them to make more credit available to higher-risk, low-income homeowners and businesses, and its efforts may very well have contributed to the nation’s current economic problems.
