HOW DID THAT HAPPEN?
Well....the people who lived there turned it into a disgusting, filthy, dangerous SLUM! It sure wasn't the whites who did that!
Cabrini Green is now long gone and guess what...it's now a nice part of town.
Though admittedly, I don't know exactly what it's like now, when I lived in Chicago, the people who lived on the Gold Coast sent their kiddos to private schools, the upscale, poshest parochial schools, or the one small Magnet school ( though after a while those kiddos went off to Latin, Park, Lab, the elite parochial Catholic and Jewish private schools , and later..off to boarding schools.
And though, when we first moved to Chicago, in the early '70s, I was shocked by just HOW segregated that city was ( and it wasn't just by race; it was by ethnicity and religion; which covered far more than just housing and schools! )and surprise, surprise...some of it was due to social strata AND choice by not only whites, but by certain ethnic groups and by blacks and "Hispanics"!
Just as the word "RACIST" no longer means a damned thing, "white guilt" is just as bogus a term now as well! So shove your lefty crap where the sun don't shine; diddums!
My wife says Philadelphia was the same way when she grew up there.
