A correlation between ethnic groups and economic disparity is not indicative of causation, much less of what the cause might be?

People having problems with even simple statistics definitely is a cause for racism on the other hand.

I find economists often to be surprisingly bad at math.

Correct. We typically understand the actual cause in the US -- historical policies promoting detrimental economic outcomes to targeted ethnic groups. I'm not sure why you interpreted my positive finding of relationship into a normative declaration of causation.
