In Systems of Survival, Jane Jacobs identifies two distinct moral syndromes--one governing commerce, the other, politics--and explores what happens when these two syndromes collide. She looks at business fraud and criminal enterprise, government's overextended subsidies to agriculture, and transit police who abuse the system the are supposed to enforce, and asks us to consider instances in which snobbery is a virtue and industry a vice. In this work of profound insight and elegance, Jacobs gives us a new way of seeing all our public transactions and encourages us towards the best use of our natural inclinations.
