Well, the author missed the point. The reason they want your children hungry (mine are homeschooled) is twofold. One, they want to be able to claim "More kids are hungry. We need more afterschool programs." Two, hungry kids are weaker and therefore are more malleable to suggestion/reward from their socialist teachers.
Yes, I am that cynical.
Maybe they are running out of ADHD drugs and want to slow the kids down again (after years of sodas and high carb diets).
