Technological change and the direction of public policy have been central to widening health inequalities between more and less educated Americans, according to a perspective published in Milbank Quarterly.
Education expansion and technology — a shifting balance
The authors review historical evidence and conclude that for much of the 20th century, life expectancy differences by education were relatively modest as primary and secondary education expanded rapidly and medical and public health technologies produced broad population benefits. But since around 1970, that pattern has altered: the life spans of people with a college degree have continued to lengthen while those for Americans with less than a college degree have largely stalled.
They attribute this divergence to a growing mismatch between the pace of technological innovation and the distribution of educational attainment. Advances in medicine, workplace technologies and therapeutics have disproportionately advantaged the better educated, while many of the economic and social risks facing lower‑educated workers have not been similarly addressed.
"The education–health gradient is sensitive to the race between technology and education."
Policy levers and potential consequences
The perspective highlights several mechanisms through which policy and technology interact to shape health outcomes. Key concerns include unequal access to new treatments and the differential impact of automation and other labour‑market changes that may deepen precarity for lower‑educated workers.
- Technological advances have delivered larger health gains for the college‑educated.
- Automation and workplace change raise the risk of job loss concentrated among less‑educated groups.
- Unequal access to therapeutics — the analysis cites concerns about novel drugs such as GLP‑1 agonists — may further widen gaps.
Without policy interventions that either decouple health insurance from employment or strengthen the labour market position of vulnerable workers, the authors warn the educational divide in health is likely to widen further.
What worked historically — and what has changed
The review suggests that the relatively narrow educational gap in life expectancy for much of the 20th century reflected two reinforcing trends: broad access to education and the deployment of technologies whose benefits extended widely. In contrast, more recent decades have seen technologies whose advantages are concentrated among those already better positioned to benefit — often those with higher qualifications — amplifying pre‑existing inequalities.
| Period | Characteristics |
|---|---|
| Up to c. 1970 | Rapid expansion of education; technologies benefiting most of the population; narrower life expectancy gap |
| Late 20th century–21st century | Life expectancy stalls for less‑educated; rapid gains for college‑educated; technological advances unevenly distributed |
The authors frame this as not an inevitable consequence of progress but as the result of policy choices about how the benefits of education and technological innovation are distributed.
Implications for policymakers and educators
For those involved in education and public health, the perspective underscores a policy challenge: improving overall population health while narrowing inequalities requires broad institutional investments whose benefits reach across the socioeconomic distribution rather than flowing primarily to the advantaged.
The analysis points to concrete policy priorities such as reforming how health coverage is tied to employment and investing in measures that protect labour market positions for lower‑qualified workers. It also raises questions about equitable access to new medical therapies and the need to ensure that innovations in care and prevention are not the preserve of more affluent or better‑educated groups.
While the review focuses on the United States, its central message has wider resonance: the interaction between education systems, labour markets, technological change and welfare arrangements can either mitigate or magnify health inequalities, depending on policy choices made today.
