Social Security was enacted in 1935. The program is officially known as the Old Age, Survivors and Disability Insurance program (OASDI). After earning 40 quarters, an individual at retirement age is eligible to begin collecting a benefit. Retirement benefits depend on your age at retirement. If you begin receiving benefits before your normal or full retirement age (FRA), you'll receive a reduced benefit. Four out of five future retirees agree that the Social Security system needs change. Many are fearful that benefits will be reduced and are unaware of the basics regarding their eligibility, participation and the monetary benefits of their Social Security profile. Sadly, 55 percent believe that Social Security will be their primary source of income in retirement.
