FYI to your racist rant, actually it's just African Americans that are athletically superior, not blacks. African Americans are genetically superior athletically due to selective breeding due to slavery and therefore physical work. This does actually confront the "baseball" comparison of the 1950's which does not relate to 2014 Facebook racial makeup.
Comparatively, horses are incredibly larger, stronger, faster, etc., than they were just a mere 2000 years ago due to the military importance of them and therefore the immense selective breeding that came of it. The reasons a few certain countries in Africa such as Kenya always win marathons is due to genetic makeups, but it's not a "black" thing it's a gene pool thing.
"Asians" in your view are actually American Asians. The Asians who come to America are financially superior than their counterparts who could not come.
However, humans are 99.9% genetically similar. There is no plausibility that any human by race could not become equal to another by another race within a few generations of genetic swapping.
