In a market capitalist system properly conceived, in order to make me better off I have to make you better off relative to what anyone else is offering you with similar resources. Competition forces me to continually improve on quality at any given price, which also means discovering ways of producing the same quality at reduced cost, and therefore reduced price. Failing to do so, I go out of business and people quit dealing with me.
Why does this seem so foreign to government school bureaucrats and those with egalitarian mindsets?
Annica Eriksson, the head cook at the Falun school, received an order from the municipality to decrease the quality of her cooking after it discovered she served a variety of 15 vegetables and freshly baked bread to students each day. The municipality claims that these offerings are “unfair” to students at other local schools, who consume meals of a lesser quality, The Local reported.
School choice (and I mean total school choice - free schools from any state mandates, including curriculum requirements) forces schools to compete for students by continually innovating and discovering ways to serve students' needs rather than the interests of teachers and public school bureaucrats.
This egalitarian ideology has had tragic consequences, leading to mass murdering of millions of people around the world throughout the Twentieth Century. This is not to say that forcing the lunch lady to reduce the quality of her meals is going to lead to mass genocide in Sweden. But egalitarianism is a slippery slope, and if it's important that something as trivial as school lunches be equal, and you're willing to force one school to degrade the quality of its lunches so students at other schools don't feel slighted, you're probably pretty far down that slope.
Here is an old post on the travesty of choice in North Carolina schools.
