So, in short, I'll be packing a bag lunch from now on, and saving about 20 bucks a month.
That, my friend, is captialism.
Most of the rest of the original post is actually promoting socialism, that is: centralized pricing based on moral outrage causing one to turn to some abstract model of what prices "should be." This line of thinking has no place in a free market. If she wants to charge $500 bucks for goddam vitamin whatever water, then great: watch her wallow in losses until she faces bankruptcy, and with any justice in the world she will go bankrupt, unless she is a bank, and then she goes crying to uncle sam for a bailout.
Anyways, a fair argument is that she does have a monopoly on school sales, whereas capitalism must endeavor to encourage competition. Do not demand she lower her prices. Demand the school system allow competition.
However, how really hard is it to bring your own lunch and "vitamin water?" I bet after water, corn syrup is the main ingredient.
