Answer: Determines the standard of life of a nation over the long term.
Step-by-step explanation:
Economists believe that the economic growth of a country determines the standard of living of its people over the long term which is why measures such as GDP per capita exist.
They argue that if the economy is growing, more wealth will be created for citizens to access and the higher production of goods and services will give citizens more choice on what to buy to be able to improve their standard of living.
