Actually 1977 with the Community Reinvestment Act ended legal redlining, so 43 years ago. My claim was that redlining still affected people as late as 10 years ago from purchasing homes. It is possible that a person born 43 years ago could not use equity in his parents home to attend a good college, and then at around age 30 didn't have the income and savings to purchase a home. Am I saying that redlining is the only reason that this potential person could not purchase a home? No. But is it OK to dismiss redlining because he could have overcome that issue? No.
Education fails minority students more. A higher percentage of minority students are in poverty. Society should do everything we can to help students in poverty achieve better results than they do. Not having stable families does hurt. Not having a structure of saving and planning for the future does hurt. However, some police officers suspecting that everyone in poverty is simply a potential criminal hurts also. Exceptional students from poverty high schools can get recognition, but good students from those schools are often overlooked. Societal restraints shouldn't be touted as an unbreakable barrier by minority leaders. However, those potential restraints shouldn't be ignored by society either. Children without a father figure are probably more likely to have issues even with society doing everything that it can, but is that an excuse for society to not do everything that it can?
A police example situation: If someone drove down the road and shot at your house, would you call the police? I am sure that you would. Would the police come and investigate the people who shot at your house? Most likely. If you lived in a poverty neighborhood, would the police automatically investigate to find the people who shot at your house, or would they suspect that maybe you are dealing out of the house and they should investigate you? If the shots didn't damage your house, or if they only cause minor damage, would you consider not calling the police to prevent a hassle? If you live in a nice neighborhood, no way. If you live in a poverty area, maybe.
I am not convinced that police interactions with minorities are purely race based. I think that at least part of it is socioeconomic class based. However there are too many anecdotal examples of middle class black men being pulled over by the police without reasonable suspicion. Maybe based on race, maybe not. But better police training and supervision to prevent pulling people over without reasonable suspicion would solve that issue either way.
