San Francisco decides happy meals are unhealthy and you should not entice children to eat them by including toys. Does McDonalds simply stop selling toys? Do they change their meals to have less fat or salt in order to keep the toy?
No, they just offer the toys for a $0.10 donation to charity if you buy a happy meal.
Sometimes you just plain can’t regulate peoples behavior. Don’t even try. Money, like life, finds a way. That is what capitalism is all about.
PS. Can I count that $0.10 as a carbohydrate-credit? How many toys do I need to buy to offset some happy fat slob who chows down on 3 Big Macs in a sitting? I smell a new therma-geddon type business opportunity!
