When the adults die, they'll leave the kids with a ruined system to work through, but since the adults never bothered to state how the corruption system works (they would lose their corrupt advantage, after all), the kids would be forced to trash the system and start anew. They would pick a good system that benefits everybody....until everybody starts having kids.
The kids, now with kids of their own, would start to grow greedy. They want their own kids to grow up to be the best, so they would leak corruption into the system to benefit their own family.
Eventually, the system would be just as corrupt, and the kids of the kids would inherit it.
In order to stop this endless cycle, why not just blow it up? We can get the corrupt parents to do it by telling Bush that Iran is about to launch nukes at us. He'll nuke Iran, which would make the Middle East launch their nukes, inadvertantly hitting the UK, who would launch nukes at all of Europe in a fit of rage, which would make Russia start nuking everybody, until finally the US just launches all of their nukes, thus ending the world.
