It seems like another life. At the height of his corporate career, Tom Palome was pulling in a salary in the low six-figures and flying first class on business trips to Europe.

Today, the 77-year-old former vice president of marketing for Oral-B juggles two part-time jobs: one as a $10-an-hour food demonstrator at Sam's Club, the other flipping burgers and serving drinks at a golf club grill for slightly more than minimum wage.

While Palome worked hard his entire career, paid off his mortgage and put his kids through college, like most Americans he didn't save enough for retirement. Even many affluent baby boomers who are approaching the end of their careers haven't come close to saving the 10 to 20 times their annual working income that investment experts say they'll need to maintain their standard of living in old age.
