When I posted this quotation
Why, indeed, do we have public schools at all? There are advantages to having an educated public, and there are at least arguments to the effect that the private sector will undersupply education. But that’s an argument for government subsidies or vouchers; it’s not an argument for the government to actually run the schools. The reason the government wants to run schools is so that it can control what is taught. I hope that makes people uncomfortable.– Steven E. Landsburg, Fair Play, p. 31
I hoped to spark an interesting debate. I did! The link at the top is to what I think is a very interesting Facebook discussion about this.
