As long as race is used as a stand-in for socioeconomic class nothing will change. The people that benefited from racist policies in the past continue to pass on those advantages to their descendants. This is particularly visible in educational institutions with legacy admissions. Groups that were disadvantaged continue to be disadvantaged because generational wealth is not something that can be "fixed" by re-balancing admissions across racial boundaries. The real problem isn't one's race but which bracket of the socioeconomic ladder one was born into.
This article overall is also kind sophomoric since it doesn't address any of the root causes of inequality and assumes race is the real issue.
