I see that some commenters on my traffic externalities post are speculating what Republicans would say about sewers if they didn’t already exist. Well, we don’t know about Republicans, but we do know what The Economist said, in 1848, about proposals for a London sewer system:

Suffering and evil are nature’s admonitions; they cannot be got rid of; and the impatient efforts of benevolence to banish them from the world by legislation, before benevolence has learned their object and their end, have always been more productive of evil than good.

Sewers are socialism!

It wasn’t until the Great Stink made the Houses of Parliament uninhabitable that the sewer system was created.
