If you want a damning indictment of the philosophy profession today, look no further than the fact that in the mind of the mainstream American, "moral leader" tends to signify "religious leader." Of course, given the meaning of "religion" in such a person's mind, this is a devastating package-deal, all rendered and accepted quite efficiently at the unexamined subconscious level; so why wouldn't "moral leader" tend to signify "philosopher"? Because (a) the mainstream of the philosophy profession has defaulted on moral theory, making it essentially useless to the community for workable moral guidance; (What moral leader is the Machiavellian-pragmatist Obama consulting these days, especially since he threw the Rev. Wright under the bus a while back?) and (b) When the mainstream American seeks moral advice on something, one can throw a stone and hit a priest, pastor, rabbi, etc. On the off-chance that consulting a philosopher for moral advice ever even occurs to such a person, how would the person know where to go?
In a perfectivism-enriched world, there would be no such problem.
