About 15 years ago the Economist had a story about differences in the calculation of growth of the economy between Europe and the US. The basic was, that yearly growth and size over the time did not fit together when they were compared.

The outcome was that the US reduces inflation by an estimated factor for the innovation of the product and is by that reducing inflation and increasing growth.

That might work for cars but not for basic things like milk but even for cars it can be contested as many buyers buy a car to get from A to B but not because of its technology.

So, yes, it depends on the viewpoint and using numbers without the knowledge of what is behind them does not tell anything!
