America spends more on healthcare than any other country. Yet if current trends hold, Americans will spend more years in poor health in 2050 than they did in 2000.
That gap—between what we spend and how healthy we are—should concern anyone who cares about the country’s future. Longer lives are a gift. But longer lives marked by chronic illness strain families, weaken the workforce, and raise public costs.
There is another path, and the US already has the tools in hand. New analysis from the McKinsey Health Institute finds that scaling proven, cost-effective interventions — not speculative breakthroughs — could add 19 million years of healthy life by 2050 and roughly $3.2 trillion to the U.S. economy.
These figures are not a “healthcare savings” story. They reflect a fundamental expansion of productive capacity: more Americans participating fully in the workforce, fewer workers constrained by illness, and fewer careers cut short by caregiving obligations.
Hospitals, specialists and cutting-edge therapies in the US are among the world’s best. However, expertise in treating disease has not translated into sustained gains in healthy life expectancy. The US system is less consistent at preventing illness, detecting it early, or slowing its progression. The result is a system that excels once patients are sick, but too often intervenes late — after costs have mounted and options have narrowed.
When disease sidelines working-age adults, labor-force participation softens and output per worker falls. Chronic, untreated, or poorly managed conditions suppress productivity through both absenteeism and presenteeism. And as care demands pull more Americans - often in midcareer - out of paid work to support aging parents or ailing partners, the labor pool shrinks at precisely the moment it needs to grow.
Rising levels of poor health also foreshadow higher long-term public spending on health, which can crowd out investments in infrastructure, education, and technology; all are critical to sustained growth.
This burden is not inevitable. According to new analysis from the McKinsey Health Institute, nearly two-thirds of avoidable disease burden in the United States could be addressed with preventive and early interventions that are already proven to work. . In addition to generating roughly four dollars in economic value for every dollar invested, these investments could yield about seven additional healthy years over a typical life.
What stands between today’s outcomes and tomorrow’s potential is not a lack of knowledge; it is the incentives to create pathways for healthier lives. This is not solely a question for hospitals or physicians but requires a fundamental reassessment of healthy life from birth to death. Health outcomes are shaped long before a patient enters a clinic — by safe and healthy foods, the environments where we live and work, education systems, community design, and the incentives that shape daily choices.
A primary care physician recently told us: “I spend most of my day managing complications we could have prevented five years ago.” Diseases become worse, leading to higher costs and less possibility of reversal. We have seen what works. Tobacco control offers a clear example. Smoking remains a significant health risk in the United States, but the scale of reduction shows what sustained policy action can achieve. A combination of higher tobacco taxes, smoke-free laws, public education campaigns, and restrictions on advertising helped drive smoking rates down from roughly 40 percent of adults in the 1960s-70s to around 11 percent today. The results have been fewer heart attacks, fewer smoking-related cancer deaths, and longer lives. These gains did not require a medical miracle. They came from consistent, evidence-based policies applied at scale. Healthier people improve economies through lower medical costs, higher productivity, and fewer premature deaths during peak working years.
Other high-impact interventions are similarly well established: controlling blood pressure to prevent heart disease and stroke, improving maternal and early childhood nutrition, expanding early cancer detection, and reducing obesity and diabetes through community-level changes. The evidence is strong. What has been missing is our collective ability to consistently incentivize and scale these things.
That requires a shift in how the nation thinks about health. We should move beyond the familiar “spend more” versus “spend less” argument. Instead, the focus should be measurable gains in healthy years and holding accountability for delivering them.
This agenda would align financial incentives so that prevention and early intervention are rewarded as consistently as treatment after illness occurs. It would prioritize scaling known interventions with demonstrated health and economic impact. It would require asking questions like, “What would it take to screen every adult American for hypertension and depression annually, and ensure access to effective treatment?”
As a society, we love to dream about innovation changing our lives through the lens of moonshots. What if doing what we know works already is our moonshot?
We should not be bound to a future in which longer lives come with more years of illness. A health reset - grounded in measurable outcomes and disciplined capital allocation – has the potential to strengthen labor supply, reinforce fiscal stability, and underpin long-term competitiveness. If the United States is serious about sustaining growth in the decades ahead, it will need to treat health not as a line item, but as part of its economic foundation.
