This can lead to higher levels of consumption of goods and services. With economic growth there will be improvement in business expectations, leading to increase in investment. Firms replace worn-out/ obsolete capital or invest in new capital. There will also be expansion of demand, leading to increased output. Existing idle capacity and unemployed labour are utilised. This result in more people being employed, thus increasing the level of consumption within the country. If human welfare is related to the level of consumption, then growth provides an obvious gain to society.
Next, it can help to avoid other macroeconomic problems. People aspire to higher living standards. Without a growth in productive potential, people’s demands for rising incomes are likely to lead to higher inflation, balance of payments crises(as more imports are purchased), etc. Growth in productive potential helps to meet these aspirations and avoid macroeconomic crises.
