Many groups have arrived poor to the US and worked themselves up to over-representation in academia and the professions, without intervention. They were not white and not always native English speakers. To further diversity should their numbers not be limited, to make space for other groups that have not exceled in the same way? If racism is such an endemic problem in the US why have these non-white immigrant groups been able to achieve over-representation in academia, government, and the professions? Why would racists allow a system that harmed rather than benefited themselves. A lot of stuff around DEI doesn't add up. It feels more like a power grab hiding behind virtue signaling.
