Notice that this argument assumes nothing about the role of nature versus nurture.
Well, if productivity and proneness to commit violent crimes depended only of nurture, the children of those people would resemble people from the country where they’re growing up, rather than their parents, so the problem would only exist for first-generation immigrants.
This is only true if we enforce strict integration of immigrant families, but where there are large populations of immigrants they tend to form enclaves where their social circles consist of other immigrants. Hence little tokyo, chinatowns, and whatnot.
I took “nurture” to refer to socialization, and it turns out that parents are much less important than same-age peers (e.g. people who grow up in a different place than their parents did end up with the accent of the former), but I had forgotten that of course literal nurture also matters.

Most people are raised largely by their parents, so the parents would have a large effect on how the children are nurtured.
