I smell a communist plot to reduce the human population. As I understand it, one can get more net calories per acre of cultivated cereal crops than one can in the same land used for pasture of prey animals. Only so much land to go around for growing anything, and even if most of the arable land is used for grass to feed prey animals there still would not be enough food do feed the current population of 7,500,000,000 (and growing) hungry mouths.
Hungry people tend to get angry when they and their kids see others well feed, and you know that only the upper echelons of society would be well feed. That can lead to riots. Enough riots can lead to governments getting to bickering. Bickering leads to fighting. Fighting leads to warring. Warring leads to lots of dying on all sides. Thereby reducing the human population to a more manageable level, allowing this scheme to successfully implemented.
Or maybe I've just been hanging around too many conspiracy related sites and forums.
Oh, and Alex Jones is actually Bill Hicks.
