Lemme run this one by you and see what you think.
The appraisal policy/valuation side of the GSEs are probably dwarfed in size by the other operating depts, and the appraisers don't have positive control over any of these other operations. It may be that they hold down a seat on the committee which is designing the horse but ends up with a camel instead.
If the data scientists there are running their big data analyses on outcomes and come to the conclusion that there's a wealth gap the appraisal dept might not have any control over that conclusion. Or maybe they did have some influence and its effect has been to either sharpen or dull the resulting conclusions being communicated. If the partisan politicians are pressuring the top executives at the GSEs to toe the official party line the company itself may have little/no way to categorically deny those demands.
One thing seems certain to me, the GSEs are not free to do whatever they want WRT the racism issue.
Speaking of, I don't know but my guess is that the recent change to the waiver program to increase the max LTVs to 97% might be entirely politically motivated, not greed motivated. I don't think it's a coincidence this just happened in late 2024, do you?
