So?
Perhaps what you really ought to be considering is the role of poverty in conviction-rates for criminal activity, which is how crime rates will be measured. People who are struggling financially not only have more dire pressures inclining them to commit crimes, but are also less likely to be able to afford the quality of legal defense that would enable them to get away with it. And who is more likely to be poor if the country operates in a racist manner? And if there is indeed systemic racism in the legal system, on top of a systemic bias against the poor in the legal system (someone rich and powerful enough is virtually above the law in the USA), that too will especially affect conviction rates.
Furthermore, you are probably thinking only of violent crime statistics, while ignoring white-collar crimes. Poor people have less opportunity to perpetrate white-collar crimes. Plus you are almost certainly ignoring political corruption, which is much less likely to be even counted as crime, because politicians make the laws, and hence the legal loop-holes that allow corruption without legal consequences.
