- Lucas: There's a number that's been stuck in my head all week: three hundred and fifty-five billion dollars. That's what RAND researchers estimated dementia cost the US economy in 2023 — and their number includes something most government reports leave out. Luna: What's that — unpaid caregiving? Lucas: Exactly. The labor of family members who are never on anyone's payroll. Once you count the hours that spouses and adult children spend helping with bathing, dressing, managing medications — the real cost of dementia is roughly double what official figures show. And that gap is going to get much, much larger. Luna: Because the population is aging fast. The number of people with dementia is expected to nearly triple globally by 2050, from about 55 million today to over 150 million. Lucas: And most countries are structurally unprepared for the fiscal hit. Let's start with the simplest economic framing: dementia is expensive because it's long. The average person lives eight to ten years after diagnosis, and for most of that time they need some level of daily assistance. That's a decade of care costs that neither private savings nor public insurance is set up to cover. In the US, Medicare doesn't cover long-term custodial care. You have to spend down your assets to qualify for Medicaid, which then pays for nursing home care — but only after you're essentially broke. Luna: So the system incentivizes financial ruin before it steps in. That seems like a massive policy failure. Lucas: It is. And it's not unique to the US. Most developed countries have some form of patchwork — a mix of family care, private insurance, and underfunded public programs. The one exception everyone points to is Japan. Japan introduced compulsory long-term care insurance in 2000, when its population was already the oldest in the world. Everyone over 40 pays into it, and everyone over 65 is eligible for benefits. It covers home care, day services, nursing homes — a broad package. Luna: And has it worked? I mean, Japan's dementia numbers are still rising. Lucas: They are, but the insurance system has shifted the burden. Before 2000, most Japanese dementia care was unpaid family labor — overwhelmingly women. After the reform, formal care utilization soared. Institutionalization rates went up, but so did community-based services. The key economic effect was that it monetized care that had been invisible. Suddenly the government had to budget for it — which meant they could see the true cost. And that forced them to make hard choices about premiums, co-pays, and eligibility. Luna: So transparency came with a price tag. The US and most European countries are still in the 'invisible cost' phase. Lucas: Right. And that invisibility leads to systematic underinvestment. Let me give you a concrete example. A 2024 study in Health Affairs looked at state-level spending on dementia care in the US. They found that for every dollar states spent on Medicaid long-term care for dementia patients, families spent another three dollars out of pocket or in unpaid time. But the state budgets only show the Medicaid dollar. So policymakers see a manageable line item, not the tsunami underneath. Luna: And if they did see the full number, they'd have to either raise taxes or cut other programs. Neither is politically easy. Lucas: Exactly. And this is the core demographic-economic tension. As the baby boom generation moves into its eighties — the peak dementia risk years — the ratio of working-age people to elderly is shrinking. In the US, it's about three to one now. By 2050 it'll be closer to two to one. That means fewer workers to support each dependent elder, whether through taxes or direct caregiving. Productivity growth could offset some of that, but not enough to close the gap. Luna: And then there's the lost productivity of the caregivers themselves. A lot of them are in their peak earning years — women in their fifties and sixties who reduce hours or leave the workforce entirely. Lucas: That's the second-order economic hit. The same RAND study estimated that unpaid caregivers in the US lost about 10 billion hours of paid work in 2023. That's roughly 5 million full-time equivalent jobs worth of labor that just disappears from the economy. And it's not evenly distributed — lower-income families are less able to hire formal help, so they take on more unpaid care, which further depresses their earnings and retirement savings. It's a vicious cycle. Luna: So what would it take to build a system like Japan's elsewhere? I imagine the price tag is enormous. Lucas: It is, but the cost of doing nothing is also enormous — it's just hidden. Japan's system costs about 2 percent of GDP annually. That's roughly 120 billion dollars for an economy the size of Japan's. For the US, a comparable system would be around 500 billion dollars a year — which sounds huge until you realize that the current implicit cost of unpaid care and Medicaid spending is already several hundred billion, and it's growing. The difference is that Japan's system is upfront and equitable. Everyone pays in, everyone gets something out. The US system is a lottery: if you have a family member willing to quit their job, you get free care. If you don't, you go broke. Luna: You mentioned earlier that dementia is long. That means the financial risk accumulates over years. How do private insurers handle that? Are there dementia-specific insurance products? Lucas: There are long-term care insurance policies, but they've been a troubled market in the US. Insurers mispriced them badly in the 1990s and early 2000s — they assumed lower utilization and higher lapses than actually occurred. So many companies stopped selling new policies, and existing ones have seen massive premium increases. The result is that the private market is essentially broken for most people. Only about 7 percent of Americans over 50 have long-term care insurance today. That's down from about 15 percent a decade ago. Luna: So the burden falls on families and Medicaid. And Medicaid is already the second-largest item in most state budgets. Lucas: Right. And dementia is a disproportionate share of that. About 40 percent of Medicaid long-term care spending goes to people with dementia, even though they're only about 10 percent of the elderly population. That's because dementia care is more intensive and longer-lasting than other conditions. The average dementia patient on Medicaid costs the program about 50,000 dollars a year. Over a ten-year course, that's half a million dollars per person. Now multiply that by the 6 million Americans with Alzheimer's today — and the 13 million projected by 2050. The math doesn't work without either a massive tax increase or a radical restructuring of how care is delivered. Luna: Let's talk about one of the potential solutions that's getting more attention: home-based care through technology. Can remote monitoring or AI reduce the labor intensity? Lucas: There's promise, but it's early. There are startups building sensor systems that detect wandering, falls, or changes in sleep patterns. Some are using voice assistants to provide reminders and companionship. The challenge is that dementia care is fundamentally hands-on. You need someone to bathe, dress, and feed a person who may be confused or agitated. Technology can augment that, but it can't replace the human touch entirely. The more realistic near-term innovation is in models like adult day care, which provides supervision during working hours at a fraction of the cost of full-time home care or nursing homes. In Japan, day care centers are ubiquitous and heavily subsidized. In the US, they're rare and often not covered by insurance. Luna: So the policy takeaway seems to be: you need a universal public system, but you also need to build the infrastructure — the facilities, the trained workforce, the regulatory framework. That's a multi-decade project. Lucas: It is. And the window is closing. The first wave of baby boomers turns 80 this year. By 2030, all boomers will be over 65. The next 10 to 15 years are when dementia prevalence really spikes. Countries that don't start building now will face a crisis of untreated needs, caregiver burnout, and exploding Medicaid costs. If walking through the economy with us has made something click about the scale of this challenge, and if today was actually useful to you, the way these stay ad-free is listener support — buy me a coffee dot com slash fexingo. Luna: Yeah, it's a small way to keep conversations like this going without ads interrupting the numbers. We really appreciate those who chip in. Lucas: Okay, back to the numbers. One more that stands out: the global cost of dementia, including both direct medical costs and unpaid care, was estimated at 1.3 trillion dollars in 2019. By 2030, that's projected to hit 2.8 trillion. That's a compound annual growth rate of about 8 percent — faster than most countries' GDP growth. So dementia is not just a health issue; it's a macro-fiscal issue on the scale of climate change or defense spending. Luna: And like climate change, the costs are back-loaded. We're making decisions now that will lock in expenses for decades. Lucas: Precisely. One of the most interesting academic papers I've read on this was by economists at the University of Southern California. They modeled the effect of a hypothetical breakthrough that delays dementia onset by five years. The result: the number of dementia cases in 2050 drops by 40 percent, and the economic savings are in the trillions. That's the kind of investment case you'd take to a venture capitalist — but it's for basic research into brain health, Alzheimer's drugs, and preventive care. The National Institutes of Health spends about 4 billion dollars a year on Alzheimer's research. That's a fraction of what we spend on cancer or heart disease, even though dementia is now the sixth-leading cause of death. Luna: So there's a huge gap between the burden and the research investment. Why do you think that is? Stigma? The fact that it mostly affects the very old? Lucas: I think it's a combination. Dementia is terrifying, and people shy away from it. There's also a historical perception that it's an inevitable part of aging — 'senility' — rather than a disease that can be treated or delayed. That's changing slowly. And the affected population, the very old, has less political and economic power. They're not in the workforce, they're not paying taxes, they're not lobbying. So the political incentives are weak. Contrast that with cancer, which affects people at all ages, including voters and donors. It's a brutal but honest explanation. Luna: Demographics are destiny, as the saying goes. And the demographics of dementia are clear: more old people, more cases, more cost. The only question is how we allocate that cost. Lucas: Right. And there are really only three ways to pay for it: families absorb it through unpaid labor and lost wages; the government absorbs it through taxes and insurance; or private savings and insurance absorb it. Every country is doing some mix of all three, but the mix determines who bears the risk. Japan has chosen to socialize the risk broadly. The US has chosen to let it fall on families and on Medicaid, which is essentially a welfare program for the poor. That means middle-class families face a stark choice: impoverish themselves to qualify for Medicaid, or drain their savings on private care. Neither is a good outcome. Luna: We've talked about Japan as the model, but are there other countries doing interesting things? I know Germany has a long-term care insurance system too. Lucas: Germany does — it was introduced in 1995, a few years before Japan's. It's a social insurance model similar to Japan's, but with some key differences. German benefits are capped, so there's still a significant out-of-pocket component. And Germany has invested heavily in home care and day care, keeping institutionalization rates lower. One thing Germany does well is caregiver support: they offer paid leave, social security contributions for family caregivers, and training programs. That reduces the productivity loss we talked about earlier. The US has nothing comparable at the federal level. Luna: So what's the single most important policy change the US could make, in your view? Lucas: I'd say creating a public long-term care insurance program, even a modest one, that covers home and community-based services. That would immediately reduce the burden on families, help keep people in their homes longer, and create a formal care workforce with decent wages and benefits. The cost would be significant, but the alternative — doing nothing — is more expensive in the long run. Every year we delay, the baby boomers get older, and the cost of catching up gets higher. If I had to pick one number to watch, it's the ratio of formal care workers to elderly people. That ratio is falling in almost every developed country. And when it falls too low, the system breaks. Luna: And that's already happening in some rural areas and low-income communities. Care deserts, they're calling them. Lucas: Exactly. Places where there are no home health aides available at any price. That's where the crisis becomes visible — and where it will spread if we don't act. So the economics of dementia really comes down to one question: Are we willing to pay now, or are we going to pay much more later? The numbers say later is more expensive, but politically, now is harder. Luna: For listeners who want to dig deeper, any recommendations? Lucas: The Alzheimer's Association issues an annual report with state-by-state data on prevalence and costs — it's free and very detailed. Also, the OECD has a great policy brief on long-term care financing across countries. Start there, and you'll see the shape of the problem clearly.
