McKinsey & Company is the most prestigious consulting company in the world, earning billions of dollars in fees from major corporations and governments that turn to it to maximize their profits and enhance efficiency. McKinsey's vaunted statement of values asserts that its role is to make the world a better place, and its reputation for excellence and discretion attracts top talent from universities around the world. But what does it actually do? Here, two prize-winning investigative journalists have written a portrait of the company sharply at odds with its public image. Often McKinsey's advice boils down to major cost-cutting, including layoffs and maintenance reductions, to drive up short-term profits, thereby boosting a company's stock price and the wealth of the executives who hire it, at the expense of workers and safety measures. McKinsey collects millions of dollars advising government agencies that also regulate McKinsey's corporate clients. And the firm frequently advises competitors in the same industries, but denies that this presents any conflict of interest.
