Younger people are sweating as America’s largest generation opts to continue working past the traditional retirement age of 65. A recent Gallup survey finds that 49 percent of boomers still working say they don’t expect to retire until age 66 or older. According to the report, concerns about money are a strong motivation for continued employment, concerns that were forming even before the recession hit.This all means that those in the younger generations may have to hold out a bit longer for new jobs or promotions. Young PhDs scrambling for tenure will probably be among the hardest hit as tenured boomers hold onto those jobs; those in more demanding and physically challenging fields will be more likely to decide to hang it up. Higher-educated Millennials and Gen Xers may expect this trend to make the job market even more competitive and their career paths harder to climb.This doesn’t mean that older people should be pushed out of the workforce. A later retirement age makes sense as older people remain healthier into their later years, and employment gives seniors a sense of purpose while also stabilizing our creaky retirement programs. The problem isn’t that older Americans aren’t retiring at the same age their parents did; rather it’s that our economy isn’t creating enough new jobs to allow both generations to coexist in the workforce.
