Why are white men the most powerful people in the world?

That why Hitler got mad when Jesse Owens was owning his German athletes in The Olympics. First he said that the Aryans had the best mental and physical abilites then he goes on and says that Blacks have better physical abilites because there from the jungle that totally contradicts his idea that Aryans had the best physical you can totally see that Hiter was talking out of his @$$ and Don't worry in the future China will become the world power the USA already owes them trillions so maybe white people WERE the most powerful people but not for long its a new area for the Chinese man.
