Yes, there are more racist countries but there are also less racist countries. The US had a history of slavery (a form of overt economic racism) which was removed in name but not deed during the civil war. At this point african americans tend to suffer more deeply specifically from the red-lining efforts of the 50's and 60's including whites-only developments. While another marginalized group, native americans, have land guarantees but a lack of land value or other assets to leverage to help fund economic growth.
White people in America have inherent economic advantages on the whole - not all white people share these advantages but there is a pretty clear correlation and there is causation: Red-lining was an intentionally racist policy that denied an economic opportunity to most African Americans.
