>Of course, there are historical reasons for why the average black family is not as wealthy as an average white one

From what I have been able to understand of writers like Kendi (see also e.g. Robin diAngelo), this statistical fact is itself, inherently, considered to be an example of "racism" (hence terms like "systemic" or "institutional" racism); and the ensuing (supposed) bias of the test towards the wealthy, another one (simply because it is ensuing).
