I have mine from 1968 on the South Side of Chicago, lone undersized white boy, other than my siblings, in an all-black neighborhood with street gangs. But Thomas Sowell remembers Harlem as a black child in a poor family, from the 1940s and ‘50s. His reminiscences are highly relevant as to what has changed since then. He is one of the greats of the Conservative movement, besides.
I have also done a fair bit of academic research reading archives of newspaper crime pages from the early 20th Century.
To be fair, many of the more lurid stories came from European immigrant neighborhoods, as well. But they weren't really considered "white" back then, with "white" meaning "Anglo."
I just kind of chafe at the current cuck-conservative trope that black neighborhoods looked like Leave It To Beaver until LBJ worked his evil Whitey spell on them.
