South Korea?
The conscription program there definitely has problems both with the treatment of the average Joe (Kim?) and the ways for the privileged to avoid risk. There will never be a perfect system (c.f. Bush essentially going AWOL when he was in the service here). But I think the circumstances are different enough - you guys already have 100% conscription, that's a big cultural difference from spinning up a draft.
I'm from a country with conscription. The major difference it makes is that the military treats soldiers like shit, because a new fresh batch of soldiers will always arrive, no matter what. In the extreme cases, your son will be found dead with three gunshot wounds and the military decides he committed suicide. In the more benign cases, you end up digging ditches with a shovel in winter, because soldiers are cheaper than machines.
