I was under the impression that it did add clarity, so I find your question odd.
What would be the charitable interpretation of the statement “socioeconomic disparities between black Americans and white Americans are due to their respective cultures”?
What’s problematic is the degree to which people can’t even entertain the idea that racism is the primary driver of these disparities, rather than things that are specific to POC, such a culture or genetics, especially given the clear and obvious precedent that is firmly established within this country.
What is a reach, is your reaction to this suggestion.
We no longer deny people opportunities based on their race. If your SAT score is high, you'll be admitted anywhere you want. If you study hard, your score will be high. The reach is constructing the SAT, or any other similar test, as racist because the scores are not evenly distributed by race.
The reason why many people cannot accept this is because many other groups experienced problems from racism as well, but they were eventually able to overcome these barriers. Moreover, the system has already changed to be more accommodating, maybe even putting most of their focus and resources on the bottom 20% of students at the expense of everyone else. Yet, we still have people stating that it’s still unfair.
