Cincinnati's Affordability Puzzle

Nick Swartsell reported on longterm residents getting pushed out of a Cincinnati neighborhood by rising prices.  The long arm of gentrification is growing longer. 

Main Street and Vinegar Hill

Vinegar Hill was an important Black neighborhood in Charlottesville, VA, which was demolished in1965, as part of urban renewal.  The pain of this is remembered by the Black community there and described in a recent article.  One of the reasons for demolition was giving Main Street "room to grow."  This photo of Main Street was taken from the foot of Vinegar Hill.  Why couldn't this residential neighborhood continue to be adjacent to Main Street?
