Advocates of using budget surpluses to bolster the social security trust fund say that:
A) the number of older Americans will increase substantially over the next several decades, eventually straining the social security system.
B) this policy would boost interest rates, increase saving, and increase private investment.
C) this policy would enable deep cuts in the payroll tax used to finance social security.
D) without such a policy, the social security system will go bankrupt in 2010.
