If you open any business newspaper or magazine, you are likely to see CEOs talking about how they are pursuing “scale” or how they will be the largest player globally in their sector in 4-5 years time.

Readers of such publications have had the word “scale” hammered into their psyche so many times that we are all more or less convinced that “scale” is the silver bullet that delivers outstanding investment returns.
