Jasani: I would guess that racial prejudice is just as rife among Mafiosi as among non-Mafiosi - maybe even more. Also, for alot of reasons, the black community in America does not have as much disposable income as the non-black community. So, it may be simply an investment decision on the part of the Mafia. They don't have unlimited resources. But I think that Puzo hit it on the head. Many people back then (and many still) didn't respect black people. And many were really, really prejudiced.
