“This study found that currently (as of 2018), a public school education in the US costs 89% more than private education; that is, $14,653 for a public school and $7,736 for a private education.”
Imagine that. If you assume that education is a “public good” (I don’t), our insistence on having public schools forces us to obtain substantially less of it than we might. We could educate almost twice as many children for the money we are spending now — all else being equal, etc.
