According to a survey of 1,064 U.S. residents between the ages of 21 and 65, low-income and younger workers are doubtful about Social Security's future. While only 51 percent of respondents between the ages of 35 and 49, and 29 percent of respondents over age 49 have doubts about whether Social Security will exist when they retire, 66 percent of respondents under age 35 think the program will cease to exist by the time they reach retirement age. Forty-nine percent of respondents with incomes between $50,000 and $75,000, and 56 percent of participants with incomes under $50,000 are skeptical about the future of Social Security, the survey finds. In addition, 70 percent of the respondents say they support the creation of personal accounts to manage Social Security funds.
