Well you see, cannibalizing children is an acceptable form of disciplinary action. You benefit the economy by ridding this planet of lazy swine that would do things to get into situations that would require disciplinary action. Furthermore, you could sate any issues with world hunger, as the hungrier a country, the more crime there is, and thus more children to eat. This system would work best under a communist dictatorship in which in the benevolent government would enforce this upon all families, adopting a 1 child per year policy to supply a steady stream of children as potential meals or model citizens, quite the opposite to the Chinese.
