Haha. It’s actually not a bad idea.
Making good health, community service and social skills a core requirement to get admission seems like a great idea. Can this also be gamed? Sure. It’s not like the existing criteria are not being gamed by families with a lot more money.
It is futile to complain about how the admission system cuts kids off from society and takes a toll on their health. Fierce competition for scarce resources is inevitable. Sure, the government can do a much better job of spending whatever resources are at hand, but even efficiency can only go so far.
This kind of out of the box thinking is more likely to yield results than pining for ideal situation that simply doesn’t exist.
