That's ignoring all of American history. Instead of investing in Black communities this country has always chosen to segregate them, isolate them, intimidate them from participating in the democratic process, and police, sentence and incarcerate them with abject cruelty.
I think the history of Overtown speaks for itself. All from
Wikipedia...
"Originally called Colored Town during the Jim Crow era of the late 19th through the mid-20th century, the area was once the preeminent and is the historic center for commerce in the Black American community in Miami and South Florida... the separate but equal segregation laws of the Deep South dictated the city designate the portion of the city, in this case, north and west of FEC railroad tracks, as "Colored Town." The second-oldest continuously inhabited neighborhood of the Miami area after Coconut Grove, the area thrived as a center for commerce, primarily along Northwest Second Avenue. Home to the Lyric Theatre (completed in 1913) and other businesses, West Second Avenue served as the main street of the black community during an era which, up until the Civil Rights Act of 1964, barred African American residents from entering middle and upper income white areas like Miami Beach and Coral Gables without "passes." During the Florida land boom of the 1920s, Overtown was home to one of the first black millionaires in the American South, D. A. Dorsey (who once owned Fisher Island), and the original Booker T. Washington High School, then the first high school educating black students south of Palm Beach.[2] Community organizing and mobilization during the era, as such in actions of Reverend John Culmer, who advocated for better living conditions for lower class blacks living in abject squalor during the 1920s, led to the completion of Liberty Square in 1937 in what is now-called Liberty City. Northwest Second Avenue and the surrounding neighborhood, once-called the "Little Broadway" of the South,[3] by the 1940s hosted hundreds of mostly black-owned businesses, ranging from libraries and social organizations to a hospital and popular nightclubs.
Popular with blacks and whites alike,[4] Overtown was a center for nightly entertainment in Miami, comparable to Miami Beach, at its height post-World War II in the 1940s and 1950s. The area served as a place of rest and refuge for black mainstream entertainers such as Count Basie, Ella Fitzgerald, Cab Calloway, Josephine Baker, Billie Holiday, and Nat King Cole who were not allowed to lodge at prominent venues where they performed like the Fontainebleau and the Eden Roc, where Overtown hotels like the Mary Elizabeth Hotel furnished to their needs. Further, many prominent African American luminaries like W. E. B. Du Bois, Zora Neale Hurston, Joe Louis and Jackie Robinson lodged and entertained in the neighborhood.[5]
The area experienced serious economic decline from the late 1950s. Issues ranging from urban renewal to the construction of interstate highways like I-95 (then, the North-South Expressway) and the Dolphin Expressway in the 1960s, fragmented the-once thriving center with the resident population decimated by nearly 80 percent from roughly 50,000 to just over 10,000.[6] The area became economically destitute and considered a "ghetto" as businesses closed and productivity stagnated in the neighborhood.[7]
