You present a new view for me, that of bringing for postive values of the black community in the 1940s and 1950s. I had suspected that a major shift came around after 1964, and the "ghetto" we know it as of today in the North didn't really exist as is shown in the media until the 1980s.
In fact, the positive media viewpoint was shown at the beginning of the "Jazz Singer" that I was rewatching which was released in 1980 and made in 1979. (I remember my mom took me a boy up in the Buffalor area where I raised). The main character, played by Neil Diamond, played in a jazz band with three black men. There didn't seem to be any negative "vibes" and the relationship seemed "normal" and genuine. Granted it's a just passing seen, but his relationship with the one black man didn't seem "forced." After that came the "crack" epidemic and the raids that put over 3 million black American men in jail, and 0 whites in jail, despites whites using and dealing crack at a higher rate and number than black Americans. This was portrayed in the documentary "Crack" on Netflix, and I haven't independently confirmed those statstics but find them to be plausible at this point. Truly one of the worst eras and most destructive if true, the rounding up of millions of black men for minor infranctions or little to no justice, most all forced to take plea bargains that reduced their chances of success in life by "marking" them and their record, making many unemployable. It did nothing to the zero number of whites for the same minor crimes. If true, that would be in line with your idea that the 1950s in Chicago had a lot of "normal" black "empowerment," meaning the owning of businesses and hospitals you list. It also means that many of the black male workers were deprived up working and own those buisnesses because of minor things done as teenagers, in what looks like a deliberate attempt to destory their community.
I apprecaited your insights and will now watch the Uncle Tom documentary to gain more insight, as it is already my list of saved films. Thanks again.
