Latest / The Demographics Podcast with Fexingo: Aging Populations, Birth Rates, and Economic Impact / How Longer Lifespans Are Rewriting the Workforce
Transcript
- Lucas: So we talk a lot on this show about falling birth rates, and rightly so. But today I want to pull on a thread that's maybe even more directly shaping the economy right now: we're just living longer, and that is rewriting the workforce in real time. Luna: Longer lifespans, not just fewer babies. Is that the angle? Lucas: Exactly. And the number that keeps me up at night, in a good way, is the labor force participation rate for Americans sixty-five and older. In 1985 it was under eleven percent. Today, it's pushing twenty percent. That's nearly double in forty years. Luna: That's a huge structural shift. And I imagine it's not just because people want to work longer. There's a financial push behind it too. Lucas: Right. The shift from defined-benefit pensions to 401s is a big part of it. A pension was a lifetime annuity, a promise. A 401 is a savings account that can run out. So people who retired at sixty-five in the 1980s had a guaranteed income stream. Today, a lot of people hit sixty-five and realize they need another decade of earnings. Luna: And that's partly why we see older workers sticking around in retail, healthcare, even warehousing. Places that used to be dead ends for younger workers. Lucas: Exactly. And the interesting thing is the wage effect. Some economists argue that a larger pool of older workers puts downward pressure on wages for everyone, especially in lower-skilled jobs. But other research suggests the opposite: older workers and younger workers are complements, not substitutes. They bring different skills, so firms can actually expand and pay everyone more. Luna: So which is it? Lucas: The honest answer is it depends on the industry. In tech, older workers might be more expensive and less productive in some roles, but they bring institutional knowledge and reliability. In retail, they often outperform younger workers on customer-facing tasks. The data is messy, but the clear trend is that employers are increasingly designing jobs that can accommodate older bodies and schedules. Luna: Can you give me a concrete example of a company that's actually redesigning around older workers? Lucas: Sure. Look at a big-box retailer like Home Depot or Lowe's. They've long recruited experienced tradespeople for part-time floor roles. But now they're adding more flexible shifts, allowing four-hour days, and focusing on ergonomic training to reduce injuries. That's a direct acknowledgment that the workforce is aging, and they want to keep those workers on the floor. Luna: And I've seen reports from Japan where they're literally redesigning factory floors for older bodies. Wider aisles, lower workstations, better lighting. Lucas: Japan is the frontier. Over thirteen percent of their workforce is sixty-five or over, which is more than double the OECD average. And they're not just doing it for social reasons. Their labor force is shrinking, so older workers aren't a nice to have, they're essential to keep the economy running. Luna: So in Japan, it's more about necessity than choice. But in the U.S., it's more of a mixed bag. Some people work longer because they want to, others because they have to. Lucas: Right. And that distinction matters for policy. If you design a retirement age around the assumption that people will keep working, you could hurt those who can't. But if you ignore longevity, you strain public finances. It's a tightrope. Luna: Speaking of public finances, how does this all interact with Social Security? The trust fund is projected to run dry in the mid-2030s, right? Lucas: Yes, around 2034 or 2035. And one of the levers on the table is raising the full retirement age, which is already sixty-seven for people born in 1960 or later. If we raise it to seventy, that would effectively cut benefits for anyone who can't work that long, unless we also add exemptions for physically demanding jobs. Luna: So the political challenge is that not everyone ages the same. A construction worker at sixty-five is not in the same position as a lawyer. Lucas: Exactly. And that's why some economists propose tying retirement age to life expectancy, but with a safety valve for those in physically demanding occupations. It's a hard sell politically, but the math is unforgiving. Luna: Let's step back for a second. If the labor force participation of older workers has doubled, that's a big deal for productivity. Are we seeing any effect on GDP growth? Lucas: Yes, but it's complicated. More workers means more output, all else equal. But older workers might be less productive in some jobs, so GDP per capita might not rise as much. Some studies suggest that an aging workforce can reduce productivity growth by up to 0.2 percentage points per year. That doesn't sound huge, but over a decade that's meaningful. Luna: And there's also the innovation angle. Do older workers slow down or speed up innovation? Lucas: There's a famous finding that Nobel laureates do their most important work in their twenties and thirties. But that's about breakthroughs. In incremental innovation, experience matters. So companies that mix ages often do better. It's not about one age being better, it's about balance. Luna: That makes sense. And actually, before we dive deeper into the productivity debate, I want to pause and acknowledge something. If you're finding this conversation genuinely useful, the way this show stays ad-free is because listeners like you support it directly. Lucas: Yeah, that's true. We don't run ads, and that's a choice. If today's episode helped you understand the workforce a bit better, and you want to keep that going, you can buy me a coffee at buy me a coffee dot com slash fexingo. It's a small gesture, but it keeps the show independent. Luna: And it really does make a difference. Every little bit helps us keep digging into these topics. Lucas: Back to the productivity puzzle. Another thing to consider is the rise of phased retirement. Traditionally, retirement was a cliff: you're full-time one day, fully retired the next. Now we're seeing more gradual transitions. Luna: Phased retirement is still pretty rare, isn't it? Most people don't have that option. Lucas: It's growing, but from a low base. Some firms offer it as a retention tool, especially for senior engineers or executives. Others are starting to see it as a way to transfer knowledge. But it's still the exception, not the rule. Luna: And for the individual, working longer can have cognitive benefits. There's research that staying mentally engaged delays cognitive decline. So there's a health argument for staying in the workforce, as long as it's not physically destructive. Lucas: That's a key nuance. The 'work forever' narrative can be dangerous for those in manual jobs. But for knowledge workers, it might be a boon. So the policy challenge is to create options, not mandates. Luna: Let's talk about the baby boomers specifically. They're a huge cohort, and they're already in their sixties and seventies. How are they reshaping the workforce right now? Lucas: Boomers are staying longer than any prior generation. But as they finally leave the labor force in large numbers, we're starting to see labor shortages in some sectors, especially healthcare and skilled trades. That's pushing employers to think about how to attract and retain older workers for longer. Luna: I read that some hospitals are actually hiring retired nurses to do part-time shifts, just to fill gaps. Lucas: Exactly. And that's not just in healthcare. Fast-food chains are recruiting retirees for management roles because of their reliability and work ethic. It's a real shift in perception. Luna: But there's also age discrimination. The AARP has documented that age bias is still common in hiring. So even if older workers want to stay, they face barriers. Lucas: That's true, and it's a waste of human capital. Some studies show that older workers are just as productive, if not more so, in many service roles. The problem is often training: companies assume older workers can't learn new tech, but that's mostly a myth. Luna: So what's the one thing a business owner listening to this should take away? Lucas: Look, the workforce is aging whether you like it or not. If you're a small business, you might already be seeing it. The smart move is to design jobs that accommodate older workers: flexible hours, ergonomic improvements, and training that uses their experience. That's not just nice, it's a competitive advantage. Luna: And for policymakers, it's about creating safety nets for those who can't work longer, while also encouraging those who can. That's a delicate balance. Lucas: Right. And the big question that remains is whether this trend will continue. As Gen X and Millennials reach sixty-five, will they stay as long as Boomers? The answer is probably yes, given that they have less pension coverage and more reliance on 401s. So we're likely to see the workforce get even older. Luna: That's a profound shift. I think a lot of people still think of sixty-five as the default retirement age, but that's becoming an anachronism. Lucas: It is. And the future of work is not just about AI or remote work. It's about an age-diverse workforce where you might have four generations in the same office. That's a challenge, but also an opportunity to tap into different perspectives. Luna: So what's the one number you'd like our listeners to remember from this episode? Lucas: That labor force participation for sixty-five-plus has doubled from eleven to twenty percent in forty years. That's not a blip, it's a fundamental change in how we think about work and retirement. Luna: It's a big shift. And it's only going to accelerate as lifespans keep extending. Lucas: Yeah, and that's the thing to keep an eye on. We're moving to a world where working longer is the norm, and that has implications for everything from savings to healthcare to urban design. It's a fascinating time to be a demographer. Luna: Absolutely. Thanks for digging into this with me, Lucas. Lucas: Always a pleasure, Luna. And thanks to our listeners for staying with us.
