Culture is an expression of biology, otherwise you'd see different cultures for the same ethnicities depending on which country they live in - instead what you see is variations on the same culture.
You're thinking of tradition, which is something that can keep people in line if the structure is strictly hierarchical, but traditions can only be destroyed, they can't really be built or re-instated, because a tradition is something that has evolved in a region over hundreds of years of hierarchical rule. Modernity can not build traditions. Absent a strong tradition a culture will emerge and that culture is going to be a function of genetics and epigenetics.
Chinese-Norwegians are similar to Chinese-Americans, who are similar to the Chinese, and their cultures are similar. Again, where there is no strong tradition to belong to.
French-Americans have similar crime rates to (actual) French people in France.
Italian-Americans have the same rate of engineers, lawyers, and doctors as Italian-Brits, or Italians in Italy.
Other peoples are 8x more likely to commit violent crime in the US, and in the UK? Lo and behold, it's also 8x. In Denmark? Well what do you know. In Africa? Ok it can get much worse than the 8x, but also the IQ gets much worse in countries with malnutrition and actual poverty.
Black culture is a superior explanation to why blacks underperform so much.
Your alternative is to just call them stupid and low IQ, but IQ has been studied extensively and does not explain everything like you claim.
