It's not exactly like that. Average IQ is very different between races. That explains many discrepancies. And it also explains these policies that revolve around cutting down the tall poppies.
Wow, I thought we left this nonsense back in the 1960s. Study after study shows that every additional confounding factor you account for lessens this supposed difference. Nutrition, health, environment, socioeconomic status, cultural attitudes toward learning, implicit bias in the IQ tests themselves, blood lead levels, iodine levels; race is confounded with hundreds of variables. The more of those you hold constant, the less you see any difference in racial averages. I suspect people who still spout this nonsense know this, and/or don't care.
