Although It Continues to Be Popular, the Social Security System

Although it continues to be popular, the Social Security system is certain to face increasing demographic pressure over time as members of the Baby Boom generation continue retiring, because:

A) Congress has not appropriately saved the monies that most Baby Boomers paid into the system.
B) the national debt will have to be paid off before all Baby Boomers can receive Social Security benefits.
C) the ratio between workers paying Social Security contribution taxes and retirees will continue to decline.
D) increasing numbers of current workers are choosing not to make Social Security contributions.
