Still on the job, more seniors find retiring doesn't work for them

Even the bulwark of Social Security is quietly retrenching. The traditional age of 65 to qualify for full retirement benefits is gradually moving upward -- workers born in 1960 and after will have to wait until they are 67 to get their full amount. In the coming years, more Social Security benefits will be subject to income tax, and higher premiums for Medicare Part B (which covers certain medical services) will further erode benefits.

These growing financial pressures may hit baby boomers particularly hard. As much as 80% of this group expects to work during what would normally be their retirement years, according to polling by AARP. Meanwhile, legal barriers to work for older people are largely a thing of the past. In 1986, the government outlawed mandatory retirement for most jobs.

"I'm not sure when I would want to retire at this point," said Claudine Welsh, 60, a Corona resident who works for a benefits administrator. She is thinking about taking on a second job and expects to work for at least seven more years. "Basically, it's because of money."

Welsh, who is single, has no private pension, and her 401(k) balance is $10,000. Home equity is key to her future economic security -- she co-owns two houses with relatives. Beyond that, she views work as an important part of life and talks about one day opening up a coffee shop with her older sister.

Otherwise, "what are you going to do with all that time?" she asked.

And there could be a lot of that. For a married couple of 65-year-olds, the odds are 83.7% that at least one spouse will survive to age 85, according to the Society of Actuaries. Chances that one will live to 90 are 63%, and chances that one will reach 95 are 35.7%.

Ten years ago, the typical age of retirement for all U.S. workers was 60, according to the Employee Benefit Research Institute. Recently, it has risen to 62 overall, a shift that researchers believe may be partly tied to the increasing reliance on 401(k) plans and the decline of traditional pensions that guaranteed monthly payments for life.

The trend could potentially have a big effect on society, putting more money in the pockets of the elderly and even giving the economy a boost, as more workers continue paying income taxes in their golden years. Research by analysts at the Urban Institute suggests that if all workers added one year to their careers, it could markedly reduce the projected shortfall in Social Security.
