Pertinent quote from the results section of the publication:
Most people who come from a socio-economically less favorable background do not commit more crime than people who come from a more favorable background, and it also happens that people from a more favorable background do commit crime. This means that even if there is a connection between socio-economic background and involvement in crime, that connection is weak. It is not possible to appreciably predict who will commit crimes based on knowledge of people's socio-economic background.

If the situation were swapped, we'd be hearing today about how Europeans had an unfair advantage because they had Zebras that are so easy to domesticate while the Africans had to deal with bullshit horses.
