Because that's what Asian parents would say, stress a bit now, be sure of an income for a lifetime.
obviously, I am not going to discount that stress does not scale well and that for children, who do not have the maturity to deal with it all, exam stress and peer pressure could lead to devasting outcomes...
but asian parents, who have long since forgotten their one-time exam stresses, but face daily stresses from inflation etc, would argue that it's worth it in the end, since they would be comparing themselves to their old classmates who didn't make the cut and are worse-off than them.

The exam themselves to tend to be absurdist, but when the seats are limited, and "fairness" is still required... asking candidates to do a special dance might be the only alternative left.
