I will add that in addition to my longer comment, I doubt that "wealth gap" has much at all to do with these differences in criminality.
Yes, the US has a high gini coefficient. But the median income is very similar to the netherlands, with NL being maybe 5000$ higher. Median wealth per capita is very similar between the two and Americans have slightly higher purchasing power, although again pretty similar. I don't think crime is higher in the US because rich people are sending the poor into a murderous rage, and if it is so then it just indicates there really is a culture problem.
