.webp "Why Rich Countries Are Running Out of Teachers and Doctors?")
The modern economy is gripped by job anxiety. New warnings appear almost weekly, predicting that artificial intelligence will disrupt livelihoods across sectors. Office roles, creative fields, and even professions once considered immune are now framed as vulnerable. That concern is not misplaced. Every major technological shift in history has reshaped labor markets.
Yet while attention remains fixed on jobs that may disappear in the future, a far more immediate crisis is already unfolding. Across developed economies, shortages of teachers and doctors are becoming acute. These roles sit at the core of social stability. They rarely vanish during recessions, and societies cannot function without them. Despite this, education and healthcare systems are quietly running out of people to staff them.
Throughout the OECD, the teaching workforce is ageing rapidly while fewer new educators are entering the profession. Teacher shortages are not new, but they were once manageable. That balance has now broken. UNESCO estimates that maintaining existing education systems alone will require millions of additional teachers globally by 2030.
The situation in healthcare is even more difficult. The World Health Organisation projects a global shortfall of roughly 11 million health workers by 2030. Ageing populations are increasing demand for care, just as large numbers of doctors and nurses approach retirement. Replacement rates are simply not keeping pace.
For years, many high-income countries relied on a common workaround. Rather than expanding domestic training, they turned to immigration to fill gaps in schools and hospitals. In the short term, this approach kept systems operational. But it depends on continued inflows and long-term retention, both of which are becoming increasingly fragile.
On paper, teaching and medicine still appear to be among the safest career choices. Teaching offers stable contracts, structured progression, and predictable schedules. Over time, salaries often rise to meet or exceed national averages. In the United Kingdom, for instance, a qualified teacher’s salary can grow from the low £30,000 range to £50,000 or more with experience, exceeding the median full-time wage.
Across the OECD, statutory teacher salaries typically fall between $56,000 and $64,000 depending on country and level taught, broadly matching the average annual wage of around $61,000.
Medical careers sit even higher. Fully qualified physicians earn well above average wages, enjoy strong job security, and possess skills that remain difficult to automate. In the United States, average physician earnings exceed $230,000 annually, compared with roughly $69,000 for the average worker. In most advanced economies, general practitioners earn about twice the national average wage, while specialists earn even more.
Despite these advantages, staffing shortages are worsening. Education and healthcare systems were built on the assumption that teachers and doctors would always be available. That assumption is now colliding with demographic reality.
For much of the last century, workforce supply followed a predictable model. Teachers and doctors were trained domestically through heavily subsidized public systems. Governments treated these roles as national infrastructure rather than ordinary market jobs. Each year, new graduates entered classrooms and hospitals as older workers retired. As long as inflows matched outflows, the system remained stable.
That balance held because demographics supported it. Populations were younger, birth rates were high enough to ensure steady labor supply, and demand grew slowly. Training capacity did not need rapid expansion.
Today, that model is failing. Aging populations are placing healthcare systems under pressure from both sides. Large cohorts of medical professionals are nearing retirement while societies themselves grow older and require more care. In countries such as Japan, Italy, and Germany, more than 20% of the population is already over 65.
At the same time, birth rates across developed economies have fallen well below replacement levels. Fertility rates near or below 1.2 are now common in countries such as South Korea, Italy, Spain, and Japan. Even historically higher-fertility nations like the UK, France, and the Nordic countries have seen sustained declines. The result is fewer young workers entering the labor force just as demand for teachers and doctors accelerates.
Training more professionals is not a quick fix. Preparing a teacher takes several years, while training a doctor often takes a decade or more from university entry to full qualification. The shortages visible today are largely the outcome of policy decisions made 10 to 20 years ago, including limits on training places and assumptions about workforce resilience.
The pandemic did not create these shortages, but it exposed and accelerated them. Burnout increased sharply, pushing many experienced teachers and healthcare workers into early retirement at precisely the moment demand surged. Once these workers exit, replacements cannot be produced fast enough.
Beyond timing, incentives play a central role. While teachers and doctors earn above-average wages, they often earn less than peers in other professions requiring similar levels of education, responsibility, and time investment. Public-sector pay structures frequently cap long-term earnings, unlike private-sector careers where pay can continue to scale.
Entry into these professions has also become more costly. Longer training periods, higher student debt, rising housing costs in urban centers, and delayed financial payoff reduce their appeal. Meanwhile, workloads have intensified. Administrative burdens, long hours, and chronic understaffing have become routine, especially in healthcare, where shortages compound stress for those who remain.
For many high-performing students, private-sector alternatives offer faster financial rewards, greater flexibility, and fewer constraints. Over time, fewer people begin training, more leave early, and the workforce ages faster than it can be replenished.
Governments have attempted to manage the problem through pay adjustments and retention incentives. But when shortages persist, the fastest solution has been migration. Expanding university capacity takes years and sustained funding. Immigration offers immediate relief and avoids large public-sector pay increases.
As a result, visa systems were redesigned to fast-track health and education workers. In the UK, this led to tens of thousands of arrivals in a single year, with health and care worker visas exceeding 70,000 in 2022 alone.
In the short term, this approach worked. Schools and hospitals avoided sudden collapses. Migration eased pressure while longer-term reforms remained slow or politically difficult.
However, migration does not create new workers. It redistributes them. When high-income countries recruit abroad, they often draw talent from regions already facing shortages. Migrant professionals are also more mobile, treating some systems as stepping stones rather than destinations.
The UK illustrates this dynamic clearly. Around one-third of doctors working there were trained abroad, along with roughly a quarter of nurses. Many contribute essential labor, but a significant share later move to higher-paying systems such as the United States or Australia. The result is continuous churn rather than stable capacity.
Fixing the problem at its source is politically and economically challenging. Raising pay strains public budgets. Expanding training requires long-term investment with benefits that arrive well beyond election cycles. Workforce plans may span decades, but the political costs are immediate.
As a result, migration is repeatedly asked to carry a burden it cannot sustain. It delays reform, increases turnover, and shifts shortages across borders.
When understaffing becomes permanent rather than temporary, systems adapt in damaging ways. In education, class sizes grow, individual attention declines, and curricula narrow. The effects may appear mild at first, but weaker skill formation today translates into lower productivity decades later. Research shows that learning quality matters far more for long-term growth than years spent in school.
Healthcare consequences emerge faster. Chronic shortages lengthen waiting times and delay diagnoses, worsening outcomes for treatable conditions. A less healthy population is less productive, with more people exiting the workforce early and healthcare systems forced to treat preventable problems.
Over time, these shortages reshape economies. Growth slows. Inequality widens as those who can afford private alternatives opt out, leaving others with longer waits and lower-quality services. Globally, the same pattern plays out as lower-income countries lose essential workers to richer systems.
In Ghana, a majority of doctors trained in the 1990s were working abroad within a few years. In Kenya, the emigration of just 167 doctors represented tens of millions of dollars in lost training investment. Today, North America and Europe employ around two-thirds of the world’s health workers while bearing only a fraction of the global disease burden.
Policy choices matter. Countries that adjusted pay, workloads, and training capacity earlier have contained shortages more effectively. Portugal steadily expanded medical education over decades, reaching one of the highest doctor-to-population ratios in Europe. Romania reversed heavy outflows by raising pay and improving conditions, sharply reducing emigration within a decade.
Technology may help, but only if used to support rather than replace essential workers. Automation and AI can reduce administrative burdens and streamline routine tasks, making these careers more sustainable instead of eroding them.
The greatest risk is not sudden collapse, but gradual acceptance. Once understaffing becomes normal, its costs spread beyond classrooms and hospitals into slower growth, weaker skills, poorer health, and a society increasingly unable to replace the workers it depends on.
Job anxiety dominates conversations about the future of work. Yet in some of the most essential sectors, the problem is not technological displacement, but the quiet erosion of the workforce itself.
