When a nation is focused on saving more this causes fewer resources to have to produce goods that were once needed at a high rate. However, because people or businesses are saving and investing, they have more capital to invest and produce more goods in the future, which in return increase GDP dramatically. Overall, when people are encouraged to save and invest it in turn provides the economy with economic growth because more is being put in that increases the rate that the country can produce. This increases both the inputs and outputs of a countries productive rates.
