One Reason for Not Requiring a Balanced Federal Budget at All

One reason for not requiring a balanced federal budget at all times is that with a balanced-budget rule:

A) expenditures are not limited because, if the government wants to raise expenditures, it just raises taxes.
B) in a recession the automatic stabilizing powers of our system of taxes and transfers could not work.
C) the distorting features of the tax system are minimized.
D) it is possible to shift the burden of a war from current to future generations.
