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.

Somebody here recommended the documentary Empire of Dust (2011), where a Chinese company gets a contract to rebuild a road between two major cities in Congo(?).
It's pretty hard to watch because you feel bad for those poor Chinese guys trying to get the locals to do anything right.
There's one poignant exchange where the lead Chinaman is shaming them for letting the road go to shit, the workers say it's not their fault the French came and built the road but left and didn't maintain it for them, and the Chinese guy I forget what he said but he's like 'are you fucking serious? it's your country how can you let it go to shit like this'.
