The premise of that proposal is that the test scores are inaccurate as a result of the economic disparity, because people with less income have less resources to prepare for the test. That would apply in the case of an economic disparity because having more resources allows you to artificially receive a higher score. It's not about accepting someone with less merit out of charity but rather about adjusting for a measurement error.

But the economic disparity is the reason for the racial disparity, because otherwise we expect people of different races are equally intelligent, right? So the economic disparity is the real one and accounting for that inherently accounts for the racial disparity as well, and you don't need both.

Which is the reason doing the latter is controversial.

That's only true if you assume prejudices like racism and sexism don't exist anymore, but they do. Even today, these are the lived experiences of many people in society. As examples, there are black people who don't get jobs because they are just assumed to be worse candidates, even when they are more qualified and put in more work. There are women who don't get jobs because they are just assumed to be worse candidates, and so on.

These are real implicit biases, and they don't go away by just ignoring them.
