I doubt they’re arguing in good faith. There is an argument to be made that we should improve education and bring more people up to speed (e.g. a lot of top10% of high schoolers can learn integration but it required a once-in-10-generations genius to figure it out for the first time). But even the most fervent blank slaters should recognise that people have different interests, and come from different educational backgrounds. The only reason to support equality of outcome is to repress high-performers.
