Presumably, the lottery is unbiased in its selections¹. Which means that the same mismatched demographics are occurring in the set of students passing the entrance exam. So it seems to me that the real problem is that the non-advanced classes aren't able to adequately achieve good outcomes for students who aren't white/Asian. Presumably, due to socio-economic disparities that cut across racial lines due to history. But instead of kneecapping the advanced students, why not dedicate more resources to those who are socio-economically disadvantaged, and start fixing the problems that cause them to be underrepresented in the entrance exam? ¹though it'd be nice if the article had researched this, since I can think of socio-economic circumstances that would cause one demographic to accept at higher rates than others.
