Richard Foster, a McKinsey director from 1982 to 2004, is a coauthor of Creative Destruction: Why Companies That Are Built to Last Underperform the Market—and How to Successfully Transform Them. In that book, he and Sarah Kaplan argue that to endure, companies must embrace what economist Joseph Schumpeter called “creative destruction” and change at the pace and scale of the capital markets, without losing control over current operations. In a recent interview with the Quarterly, Foster offered his view of how the current financial crisis might change the business world and the capitalist system.
