You have to think of it like the nutritional supplements industry. They make mountains of money because people have certain misgivings or insecurities or unrealistic goals (or all of these things) with regard to their health. Would life go on just fine without the entire supplements industry? Sure. But that wouldn’t do anything to assuage the health concerns that people perceive themselves to have.

The same is true of the consulting industry. Because companies _also_ have certain misgivings or insecurities or unrealistic goals with regard to their health.
