How is it a zero-sum game? When one person learns more it does not mean others will learn less. The opposite is true, the person who learns can then teach others.

The government should be able to provide enough education to anyone who needs it. But to do that they need many teachers. Somebody must educate the teachers. More learning overall grows the intellectual capacity of the whole nation, it is not a zero-sum game.

I seriously think this is about Chinese Government not wanting its population to be educated in Western values.
