How much federal revenue will medical spending consume by 2040?
Core argument: David Cutler projects U.S. medical spending reaching 26%, 22.3%, or 19% of GDP by 2040 under high, benchmark, and low scenarios, versus 18% in 2024 and 6.9% in 1970.
Figure 1 shows that in 1970, medical care was 6.9% of GDP. In 2024, it was 18%. From 1970 through around 2010; mean medical spending growth exceeded GDP growth by 2.4 pp annually. Since 2010, the growth of medical spending has exceeded the growth of GDP by only 0.3 pp annually. There is no comparable time period with anything like the sustained slowdown in spending growth since 2010. Patient cost-sharing has increased enormously [indirectly reducing overall expenditure via incentives] as shown in Figure 5. An additional role [was] played by the diffusion of cost-reducing technologies. Because they are often less invasive, second-round therapies typically have lower unit prices. [mechanism in Fgure 6]. Finally, there [are] fewer expensive new innovations than in the past. [However], recent data show an uptick in spending growth in 2024, which continued in 2025. Some of this is a result of new technologies— prime examples are GLP-1 medications and new drugs for cancer that are taken on an ongoing basis. To consider a scenario with [a reversion to] more rapid spending increases, I assume that the growth of medical spending above GDP growth after 2024 returns to the average rate realized between 1970 and 2010. This scenario is shown as the High-spending scenario in figure 1, in which medical care in 2040 rises to 26% of GDP.




Ed Comment:The numbers in this article don't seem to add up. It says 30 mm are uninsured. Then it details 10 million and seems to call it 2/3s. Then it has a category zero million.
Ed Comment:Hard to see that 100mm people are at risk of losing coverage and/or can't get HC. 20 mm are subsidized and don't take it. 2.6 can afford it and don't take it. Half of the remainder are illegals. Many people won't be very sympathetic to them and we still give them some/essential HC so it looks like 3 of the 30 might want it but can't get it. The rest are all covered. That said, I still don't know how many people with pre existing conditions significant enough to truly prevent them from being covered are being "saved" by obamacare. (The ones with employer coverage would get it). So it looks like the true number is at risk is much smaller than 100mm Can you please take all your entries and sort everyone into buckets including the elderly. One bucket would be resting conditions covered by employers. It would be great to see those who were eligible for Medicaid and chips without Obama care and those who were added to it because of Obama care. A clear top down picture would be useful/enlightening.
Jim Capretta Comment:"Thank you for pointing this out (not sure why no one else did). Some numbers got lopped off in the translation from what I submitted to what got posted. Here are the correct numbers in order of the first bulleted points: 5.1 million people 5.5 million 9.4 million Then in the next bullets it should be: 4.0 million 2.6 million I hope this is clear enough.”
Ed you were right, 30mm persons < 65are currently uninsured, but I can’t line his numbers with the reports, according to theCBO(See Figure 1, 67% of uninsured persons are currently eligible for subsidized coverage) Before I sent you a note that it was wrong I wanted to confirm with him, he said it was a typo on AEI’s part.
Capretta, "...In 2019, 12 percent of the nonelderly population — or about 30 million people — went without health insurance..."

Steve Comment:I’m still working on thenumber of individuals with pre-existing conditions who currently get coverage through employment and the number who are buying it on the exchanges due to the ACA. This is proving a little hard.But I wanted to show you a topdown snapshot of the <65 population,90% are covered if you exclude illegal immigrants. (According to theKaiser Family Foundationanother67.7mm >65 individuals are enrolled in Medicare in 2020.)According to CBO 155mm (57%) of the 272mm individuals < 65are covered by employment based coverage this year. But in terms of the number of people < 65 “saved” by Obamacare in 2020 CBO estimates13mm(so 5% of <65) individualswere added to Medicaid due to the ACA.See table A-1. In total70mm (28%)individuals <65 are covered by Medicaid. Note one thing from footnotes as this caught me up “The components do not sum to the total population because some people report multiple sources of coverage. CBO and JCT estimate that in every year of the projection period, between 12 million and 14 million people (about 5 percent of the insured population) have multiple sources of coverage, such as employment-based coverage and Medicaid”
