She is, alas, destined to be disappointed by reality:
First Lady Michelle Obama held a news conference last night, where she predicted that one day, children would go out on Halloween and beg for healthy food instead of candy.

Just imagine what it’s going to be like moms and dads when our kids are begging us to buy them fruits and vegetables instead of cookies, candy and chips,” Obama said.
Nothing to prevent that from happening, I guess, except human nature and all of human experience throughout history. Certainly kids can be brainwashed to believe such nonsense as "Recycle to Save the Planet!" and "Global Warming Is Killing You As We Speak," but getting them to beg for spinach and carrots on Halloween would be beyond the powers of the Chinese in "The Manchurian Candidate" who were able to turn an ordinary soldier into a homicidal maniac. Kids don't want what's good for them. They want what they want. They're kids.
