There are often inconsistencies between how people define their own financial responsibilities and how willing or able they are to save for retirement. Few Americans say individuals should be asked to pay for a greater share of the nation's retirement system. And although less than one-quarter of Americans believe Social Security will be able to pay them full benefits when they retire, majorities say they're confident about having enough money to live comfortably. Yet few have calculated how much they will actually need. Furthermore, most Americans believe that most people don't save enough money for retirement.
