It makes the point that racism does exist, but its key point is that there are greater factors in play that affect the outcomes of the younger generation than just racism,
It would appear that Dr Sewell argues that factors such as poor housing, low aspirations, front-line (zero hours contracts), etc are more important than ethnicity in why ethnic minorities under-perform compared to their white counterparts.
However Dr Sewell fails to ask the all important question: "Why are ethnic minorities in that position?"
If he had asked that question, it would have been obvious to him why prejudice and discrimination is a major factor in inequality in UK.
racism is a easy card to play as a reason for inequality when there are other significant factors that are being ignored. EG Why do children of Black African heritage outperform children of Afro Caribbean heritage despite being in the same classrooms.
I believe Dr Sewell presented this as his justification for why racism is not an important factor in inequality.
However, he presents the answer, yet fails to realise that it is the answer.
African immigrants who perform well tend to be first generation immigrants and have not suffered discrimination and prejudice since birth. Therefore their aspirations and ambitions have not been supressed by a racist society. Subsequent generations of African immigrants become the product of inequality and suffer the same reduced aspirations.
Those of Afro Caribbean heritage tend to be second or subsequent generation of immigrants. They and their parents and older relatives have been oppressed in UK from prejudice and discrimination. They are the very product of years of inequality, and continue to be so. They are the children of the Windrush generation that consider themselves British, but the system does not.
Yet again, we find ourselves in the situation where anyone that says that there may be other factors in play other than racism is denounced as a racist or a victim blamer to shut down the discussion.
No-one is trying to or wants to shut down the discussion, except perhaps Dr Sewell, who was employed by Boris Johnson to head a commission, when his conclusions were already well established eleven years ago, and several members have not only disagreed with the conclusion, but have stated that their views have been misrepresented, or not represented at all. Additionally, Boris Johnson has espoused overt racist comments in the past.
If Dr Sewell wants to raise the aspirations of ethnic minorities, and thereby reduce inequality, by arguing that those that suffer the injustice of inequality have the ability to rise above it, then a) you cannot rise above a structural problem by simply ignoring it, and b) arguing for such an approach alienates those who are acutely aware of that structural inequality from their own experiences, and c) gives those who have the ability to affect inequality, an ideal excuse to do nothing, and d) gives racists an ideal opportunity to deny that racism is a problem in modern day societies.
We know that BJ's mantra is to do as little as possible, and to do it as slowly as possible.
