Our world has become more complicated, and the notion of growth at any cost has led to constant economic uncertainty, a permanently stressed-out workforce, and everyday stories of government and corporate abuse. John K. White argues that a better knowledge of basic systems is needed to understand the world we live in, from pyramid scams to government bailouts, from sports leagues to stock markets, from the everyday to the seemingly complex.
