That's not a bug, it's a feature. Increasing educational anxiety is precisely how these policies should function. One of China's most entrenched pathologies is the perverse incentive to pour inordinate resources into educating a single child. That will no longer be a viable strategy when any brat could take that coveted university spot away from the child you poured your life's work into educating just by dint of having a sibling.There was some criticism of the Weifang and Zezhou policies that they would increase educational anxiety.
It goes without saying that these policies should function in tandem with increasing educational resources.
