It's happening. The Melonheads reserve fresh grass-fed beef, garlic, chocolate and other extremely healthy foods for their ruling classes. They had these proscriptions in Sumeria, India, Egypt and most other nations they reigned over throughout history. The peasants have always been fed gruel. Lately they have been talking seriously about trying to wean the commoners onto a diet of insect slurry. This of course would be a natural progression towards Soylent Green. One day you'd be slurping on your Big Worm Gulp and you'd find out that is no longer mealworms in there. It is human livestock being recycled.
Melonheads know that meat makes strong and they don't want strong slaves. They want them vaccinated and fed carbohydrates so they grow up to be the living dead.
