> Infrastructure, essential as it is, can't be justified in strictly commercial terms. The payback period for things such as transportation and communication systems is too long for standard investment, so you get government-guaranteed instruments like bonds or government-guaranteed monopolies. Governance and culture have to be willing to take on the huge costs and prolonged disruption of constructing sewer systems, roads, and communication systems, all the while bearing in mind the health of even slower "natural" infrastructure—water, climate, etc.

> Education is intellectual infrastructure. So is science. They have very high yield, but delayed payback. Hasty societies that can't span those delays will lose out over time to societies that can. On the other hand, cultures too hidebound to allow education to advance at infrastructural pace also lose out.
