Erich - I forgot Pasadena. You will find the areas declared blighted and bulldozed underneath the 210 freeway.
All across the country, in one city after another, the destruction of America's "Black Wall Streets" was "systematic" meaning people had choices.
Nothing in the law - or constitution - dictates the location of a freeway, a damn, or a toxic waste dump. We can't blame a system for choices "we" make on our own. Freeways are sited by choice - meaning people make an intentional and purposeful decision to bulldoze one community, rather than another.
