The first term is the reciprocal value of the duration of the period of mean income growth with work experience, Tcr. The current value of Tcr in the USA is 40 years. The second term is inherently related to population and defined by the relative change in the number of people with a specific age (9 years in the USA), (1/2)*dN9(t) /N9(t), where N9(t) is the number of 9-year-olds at time t. The Tcr grows as the square root of real GDP per capita.
Hence, evolution of real GDP is defined by only one parameter - the number of people of the specific age. Predictions for the USA, the UK, and France are presented and discussed. A similar relationship is derived for real GDP per capita.
That may be an alternative way of estimating GDP Growth, but its not actually what GDP growth is.
A better measure of "well-offness" is GDP
per capita or growth in GDP per Capita.
A centralised government may only be interested in total GDP because its a measure of how much resources they have to throw around compared to other countries. So a central government may not care if GDP per person is decreasing, so long as total GDP is increasing.
Eric Jones (British) wrote a great book called "The European Miracle" which looks at 1000 years of economic growth and develops a theory of why economic growth in European and Western countries has over a very long period of time outstripped other economies. An alternative theory was developed by North and Thomas (Americans), but Jones it better (IMO). If population growth was the key driver, India and China would have outstripped western countries.
People (and economies) adjust to their environment. Its countries where the power of the state has been mitigated, giving people more freedoms, which have the strongest growth. America has been so successful because of its federation of states, each (if only subtly) in competition with each other and keeping total power away from teh central government (although you may not think so, its historically true, relatively speaking). Likewise European countries "competed" against each other. This put a limit on the control of the state that non-western countries did not have.
IMO increasing centralised power is the greatest threat to a successful economy.
