The CIA gini coefficient is slightly higher for the US, a few percentage points, while the World Bank Gini coefficient is slightly higher for China. Your conjecture about the starker divide between rich and poor in US cities is just that, conjecture. I could guess the same about Chinese cities. So we have no evidence yet that China has less income inequality than the US. Which makes it a very unconvincing reason for differences in crime.
