I think the problem is more about skill floors than skill ceilings. I never really cared that much about Asian's positive stereotypes, but the same arguments have been used to propose arguments that hispanic/black students are inherently inferior. Despite the face that much of that, was and is environmental issues.

Once you hit a certain point, sure. There will simply be people who's brains work differently and efficiently, similar to runners who have different pique physiques for their respective category (I don't think we even tap into half of that in classical public teaching but I digress). But it's a much bigger sale to say that some people simply can't pass high school level acedemics and use that against them.
