Many of the protesters currently occupying American cities and engaging in actions around the world are angry at what they say are the worst offenders – companies and people taking unfair financial advantage in a capitalist system. Some argue that capitalism is broken, but is that true, or is it just that some are “gaming” the system? Dean of the Rotman School of Management at Toronto University Roger Martin thinks it may be the latter. Author of “Fixing the Game: Bubbles, Crashes, and What Capitalism Can Learn from the NFL,” Martin argues that an economy based on “real goods” rather than risky futures trading and other financial instruments, is the key to stable capitalism.
