More than 50 million people receive benefits totalling more than $600 billion a year. Originally established to provide retirement benefits, the program was extended to widows, the disabled, and children in some cases. It is estimated to keep 40 percent of the elderly out of poverty. Currently, retirement benefits are paid to people when they reach the age of 65, though younger people will have to wait until they are 66 or 67, depending on the date of their birth.
