Is the USA racist?

John Christopher Smith (JSC) was only 12 years old when he started working at J & J Cafeteria owned and managed by the family of Bobby Paul Edwards in 1996. Six years later, when Edwards became manager, he stopped paying JSC and that's when the abuse began. JSC a black man ailed with a mental disability was subjected to torturous, physical and mental abuse that carried on for 17 years until 2014; when Geneane Caines, a white woman, who noticed a scar on JSC's neck when he came to put some food down, reported Edwards' behaviour to the authorities. The story says Edwards kept JCS from his family but I don't understand why his family did not go looking for him or make a stink when they did not get to see him. Tim Scott says the USA is not racist but I believe selling that narrative does very little to address the racism that continues to pervade the country whether blatant or systemic. The facts of this story read like something that happened 100 years ago but the whole ordeal was only revealed in 2014. More people need to call out this scourge on society, more white people as Geneane Caines did. And more black people need to recognize when they are being treated unfairly and speak out against it without fear of reproach.
