Asians are superior to whites, but whites had luck on their side and asian societies didn't develop as well. Arabs were at one time superior to whites, but their society was destroyed by religion. Mayas and other civilized indians got close, but their society too was plagued by religion and developement was stagnant for long time. Blacks were also attempting to build a lasting culture numerous. Nubia which was essentially wannabe Egypt was black nation and it actually worked for some time, but eventually collapsed and no-one remembers it today. Basically key to white people's success is luck and adaptive changing society.
