… is from pages 449-450 of the 5th edition (2015) of Thomas Sowell’s Basic Economics:
The top priority of an elected official is usually to get re-elected, and that requires a steady stream of favorable publicity to keep the official’s name before the public in a good light. The opening of any major new facility, whether urgently needed or not, creates such political opportunities by attracting the media to ribbon-cutting ceremonies, for example. Filling potholes, repairing bridges, or updating the equipment at a sewage treatment plant creates no ribbon-cutting ceremonies or occasions for speeches by politicians.
If you want better infrastructure, privatize it.
