It's irrational to expect every human racial group to achieve at exactly the same level in every area of life and human endeavor. Of course ethnicities will commit crime at different rates, and have collectively differing IQs, for example. Maybe the differences will be modest, but it would be truly miraculous if there were no statistical differences at all.
I'm not an Ashkenazi Jew, but I recognize that as an ethnic group, there have been studies suggesting that they, on average, have a higher intelligence than my ethnic group. Whether this is primarily due to their nature or their nurture, I do not know, but I accept that it is very likely true. Some racial disparities are obvious, others are not.
All of this doesn't matter to me much because at the end of the day, as a Catholic Christian, I believe that all men are made in the image of God and the metrics that God will judge humankind on is right and wrong, good and evil. Your race, your intelligence, your beauty and your physical strengths are all accidents of your birth and not virtues or vices. Not everyone can be Tom Brady or Aristotle. But anyone can be a saint. Loving your neighbor as yourself is a matter of the will. How morally good are you? The greatest man is the man who is most moral/virtuous/godly.
