A letter writer in the April 27, 2008 Wichita Eagle makes the case that investment in USD 259 (the Wichita, Kansas public school district) has a good return.
By way of comparison, the writer argues that the Wichita airport, having been built with public funds, represents "an investment return." Whether it represents a good return on investment the writer doesn't say, but I believe he means that the airport was a good investment of public funds.
