(CNN) - Pessimism over Social Security is at an all-time high as six in ten Americans who don't already receive benefits through the program say they never will, according to a new CNN/Opinion Research Corporation poll.
As the program nears its 70th anniversary of implementation, 63 percent of Americans say the program won't last another 70 years.
"There have always been a significant number of Americans who thought that Social Security would not be able to pay benefits to them when they retire," CNN Polling Director Keating Holland said. "But since 1989, when Gallup first asked this question, that number usually hovered in the mid-40s and never rose higher than 52 percent. Today, 60 percent say they will never get a benefit from Social Security."
Only about four in ten of current retirees believe Social Security will always be able to pay their full benefits, according to the poll.
For the first time in nearly 30 years, Social Security will pay out more benefits than it receives in payroll taxes both this year and in 2011. By 2015, the program is expected regularly operate with an annual deficit.
The poll was conducted on August 6-10 and surveyed 1,009 Americans, including 935 registered voters. The sampling error varied-from 3 percent to 5.5 percent-by question. The full results of the poll, including the sampling error for each question, may be found here.
