Answer:
C) Increase the growth of real GDP per person for several decades.
Explanation:
Currently, the U.S. government is running a deficit of about 4% of GDP. This deficit affects economic growth, it causes tax increases or even more debt, and it leads to the misallocation of resources.
If the U.S. undertook a policy to increase national saving, it could reduce the deficit, or even, run a surplus. Under a surplus budget, the government could reduce taxes, or keep them low, and use most of the tax revenue for investments that produce growth, for example: infraestructure.
