Your article basically says auto dealers are racist but federal contractors and "profitable companies" are generally more comparable. The solution would be to enforce racist regulations against the auto dealer, not falsely generalize the problem and enforce a solution. Secondly, there are fields of academia that make it a point to show racism exists and to uncover racism, so publications like this are as fraught with conflicts of interest as a cigarette company researcher investigating the benefits of nicotine. Pointing the finger at white people is also problematic, it's a racial supply/demand, and generally at competitive fields like medicine or programming, competitive schools, one sees a proportional oversaturation of asians (per capita) versus whites. Shall we say employers are favoring asians and talk about the asian menace, as we do the white menace? If particular races, often tagging a cultural history, are associated with different cultural preferences for lifestyle or career, I would simply say "so what?" If the goal is to homogenize equal participation from all demographics groups to all vocations, to me that seems silly and runs against human nature, it can be expected to work as well as the communist efforts of societal homogenization we saw in the 20th century. Yes, we need to kick the tires and convince ourselves that all are afforded somewhat fair opportunities, but seeing race as a confounder here or there, and immediately leaping to systematic racism as the purported mechanism - that's just poor science.
