This phenomenon was observed by anthropologist Elliot Liebow in his ground-breaking book, Tally's Corner. What's sad is that the ghetto behaviors of the African-American underclass have remained so much the same after the Great Society program has poured $20 TRILLION primarily into the A-A community.
Liebow was a first-generation American of Russian Jewish extraction with a swarthy complexion and dark curly hair. He spent 18 months hanging out in a black DC neighborhood to research his doctoral thesis, on which he later based Tally's Corner. It was, and is, a very compelling book. Here's a 2011 article about it:
44 years later, Tally's Corner is revealed
Thanks, I do remember that book. His observations were very good.
The problem with the ghettoes is that they were a moral chaos. After all, some of the residents came out of families from slave states with areas that did not allow African slaves to receive religious instruction or even be baptized, and in fact there were some counties in Georgia that, at least in theory, would punish missionaries by death (although this was never carried out, to my knowledge).
Once the “Great Society” came along and made the government everybody’s daddy, it was all over for what was a very fragile social structure in black communities.
