Indicadores definidos numa e para uma época, são incapazes de captar as subtilezas da mudança do mundo, por exemplo o caso do comércio online e as vendas no retalho físico.

Ainda ontem se escrevia aqui "Acerca dos números do emprego". Por isso, recomendo a leitura de "Time to say goodbye to the unemployment rate":
"The unemployment rate is a recent invention designed for limited purposes, yet it has come to assume totemic status in a way that makes it almost impossible to have a cogent discussion of labor in the United States (or anywhere else in the world that keeps similar numbers) and design meaningful public and private responses to our challenges.
...
the grand illusion of the unemployment rate and indeed of all of our leading statistics and indicators. We treat them as absolute markers, and reliable guides to our world. They are not. They are numbers that we invented remarkably recently and that then assumed a place of importance in shaping our sense of the world out of proportion to what they can and do measure.
...
There is, therefore, no unemployment rate, at least not as currently understood. There are multiple rates, by race, by gender, by geography and above all by educational attainment. When people talk of an unemployment crisis, it would be more accurate to speak of an education crisis or a crisis of men whose skills are mismatched to the jobs of today. It would be more accurate to speak of a jobs crisis in specific regions of the country, or for specific industries such as heavy industry. Yet, we maintain the collective fiction that one simple average accurately captures a multiplicity of realities."
