I would push on how well GDP measures "economic might".

If I were to tell you a country over five years grew its GDP 5% in 1900, that would mean houses and roads and factories and mines and a whole range of things were built.

In 2020, 5% real GDP growth could be an increase in the value of various services. In fact, you might not need to change the physical world at all to achieve that growth.
