"At its core, the goal of education is to prepare individuals for employment and advancement" No. It should help a person develop into a free, thoughtful, well-rounded human being. Training narrowly for current market demands can become obsolete quickly. The question should not be: Should education have economic value?

What do these words even mean, and why should taxpayers pay for that? Is there any institution today that teaches you to be a “well-rounded human being?” Do students graduate being able to hunt for food, grow crops, or build a house?
There might be great value in whatever type of “education” you’re talking about. But “education” as a public, taxpayer supported activity is about the economy.
