“How does she have so much power?”
The answer is quite obvious. She has the power because PEOPLE GIVE IT TO HER. There is no law that requires schools to answer to the federal government when it comes to their lunch menu - but there is a price you pay if you want money from the feds for school lunches.
We’re complaining to the wrong people. She would be POWERLESS if local school districts simply told her to take a hike, and ran their lunch programs by either using taxes (if they really think they need to subsidize) or simply charging kids for the food. If the kids don’t have the money (mom spent it on drugs again, for example), then the kids don’t eat - no different than today, when they get a Michelle-meal and throw it out anyway.
Wanna bet that better food in greater quantities will be offered to students who volunteer to work for the regime?
