No Idea. I'm pretty sure they WERE filtering learning though the lens of children being on an assembly line, reading to be factory sealed for the workplace. All that matters is the answer. Who cares you if got the brains or can work things outWere they filtering that idea through the lens of race or not?
Edit: I'm also talking about Australia here. So the flippant 'no idea' is a definite no. I am aware that other countries had similar problems but not conscious of what the argument was exactly and their proposed solution
