A Major Concern About the Rising Transfer Payment Obligations of the U.S

A major concern about the rising transfer payment obligations of the U.S. government over the next decade is that:

A) unusually high rates of inflation are forecast, leading to rapidly rising obligations for fixed-income recipients.
B) the numbers of elderly people are decreasing due to unaffordable healthcare.
C) rising tax burdens will lead to unnecessary budget surpluses.
D) the demographic composition of the population is changing, reducing the number of taxpayers per transfer payment recipient.
