Ultimately, it may not be the right idea. Perhaps 3 percent for children's causes is too much (or perhaps too little). Perhaps enshrining that idea in the charter really isn't a good idea (though San Francisco has hardly fallen off a cliff, nor has Oakland, which did something similar in 1996, nor Miami, which followed several years later). Maybe it would be sufficient for the City Council to establish an oversight board for these sorts of investments through statute and pressure this and future mayors to fund it adequately. Maybe some other cause — job training for adults, transportation between the inner city and employment centers, re-entry services, addiction treatment or something else entirely — would have more impact. Mr. Young readily admits that his proposal may not be the answer.
