A survey of more than 1,000 investors suggests they would like more control over their retirement savings.
Sixty percent said they would support a program that would let them make investment decisions for a portion of their retirement contributions, according to the survey by Roper Starch Worldwide of New York.
Meanwhile, 49% said they dislike the idea of the government investing part of Social Security funds in stocks.
Seventy-two percent said individuals should be responsible for ensuring adequate retirement savings, compared with 35% who said it is the government's responsibility.
The study, done for Massachusetts Financial Services of Boston, also showed that only 26% would keep the current Social Security system.
Despite concerns over Social Security, 66% said they believe their standard of living will remain constant after they retire, and 19% believe it will rise.
