This is quite simply factually false. Socioeconomic status (so-called "privilege") has some correlations with outcomes, but there's wide variation in abilities even once you account for socioeconomic status. Every kid is unique, and pretending that the top 5% of learners should be in the same classroom as the bottom 5% of learners does a disservice to both.
