Many of us remember the 1970s for its music and fashion, but we should also take a lesson from its mistaken beliefs. Without easy access to data or analyses of social trends, some ideas about the workings of nature and society were completely backward. Today, we know things that were simply unknowable back then.
If you asked doctors in the 1970s who was most likely to suffer a heart attack, they would share an intuition about “executive stress.” It was believed that people in senior leadership positions faced higher risks of coronary disease because of the demands of their jobs.
It turns out that there is no such thing as executive stress, and heart disease is far more common — and deadlier — in people further down the socioeconomic ladder. Politicians and policymakers (and of course physicians) now know about health inequalities and the link between social status and morbidity, even if they do not always act effectively to address it.
In the UK, this discovery dates back to 1980, when the now-defunct British Department of Health and Social Security published its Report of the Working Group on Inequalities in Health.
The Black Report, as it became known (after its chairman, Sir Douglas Black of the Royal College of Physicians), systematically collated all the available data on socioeconomic status and health outcomes. Men in the lowest socioeconomic group, it turned out, were dying at a rate twice that of men in the highest, and the gap was growing, despite the establishment of the National Health Service.
Then-British prime minister James Callaghan’s Labour government commissioned the Black Report in 1977, but by the time it was published, former British prime minister Margaret Thatcher’s Conservative government was in power.
In its 2002 obituary for Black, the British Medical Journal said: “The Black report was not to Mrs Thatcher’s liking and was never printed; instead, 260 photocopies were distributed in a half-hearted fashion on Bank Holiday Monday.”
And, although “the report had a huge impact on political thought in the United Kingdom and overseas” — leading the Organisation for Economic Co-operation and Development and the WHO to assess 13 countries’ unequal health outcomes — this did not extend to “UK government policy.”
Just as Thatcher’s government was burying the Black Report and pretending that health inequalities did not exist (and, indeed, that “society” did not exist), it was also pursuing neoliberal economic policies without any evidence to support them. These measures included reduced public spending and the privatization of public goods, lower taxes, financial deregulation and free-trade agreements.
In the late 1970s and early 1980s, neoliberalism’s defenders promised that embracing market-based solutions would unleash economic growth, generating the proverbial rising tide that lifts all boats. However, like executive stress, this phenomenon was a phantom. That did not stop Thatcher and then-US president Ronald Reagan from pursuing an agenda that disrupted the health and wellbeing of millions of people. In the face of growing inequality, they saw the gap between rich and poor as just a side effect, and possibly even a spur for innovation, aspiration and creativity for those lower down the ladder.
They were wrong about that, too. Even before the 2008 global financial crisis, neoliberalism was causing what the University of Durham’s Ted Schrecker and Clare Bambra have called “neoliberal epidemics.” As Schrecker and Bambra and many others have shown, income inequality has profoundly damaging and far-reaching effects on everything from trust and social cohesion to rates of violent crime and imprisonment, educational achievement, and social mobility. Inequality seems to worsen health outcomes, reduce life expectancy, boost rates of mental illness and obesity, and even increase the prevalence of HIV.
Deep income inequality means that society is organized as a wealth-based hierarchy. Such a system confers economic and political power on those at the top and contributes to a sense of powerlessness for the rest of the population. Ultimately, this causes problems not only for the poor, but for the affluent as well.
One problem in the past was that income inequality — and its link to social and health problems — was overlooked in comparison with measures of national wealth, such as average income (GDP per capita). However, as leading economists and institutions such as the IMF and the World Economic Forum are coming to realize, income inequality is a serious problem for economic stability and growth, too.
Careful analysis of statistical data debunked the idea that stressed executives are at a higher risk for heart attacks. Now, it has debunked the 1980s myth that “greed is good,” and has revealed the extensive damage inequality causes. It was one thing to believe these myths decades ago, but when experience and all the available evidence show them to be mistaken, it is time to make a change.
“Any man can make mistakes, but only an idiot persists in his error,” the Roman philosopher Cicero said. Now that we know how inequality harms the health of societies, individuals and economies, reducing it should be our top priority. Anyone advocating policies that increase inequality and threaten the wellbeing of our societies is taking us for fools.

The conflict in the Middle East has been disrupting financial markets, raising concerns about rising inflationary pressures and global economic growth. One market that some investors are particularly worried about has not been heavily covered in the news: the private credit market. Even before the joint US-Israeli attacks on Iran on Feb. 28, global capital markets had faced growing structural pressure — the deteriorating funding conditions in the private credit market. The private credit market is where companies borrow funds directly from nonbank financial institutions such as asset management companies, insurance companies and private lending platforms. Its popularity has risen since
The Donald Trump administration’s approach to China broadly, and to cross-Strait relations in particular, remains a conundrum. The 2025 US National Security Strategy prioritized the defense of Taiwan in a way that surprised some observers of the Trump administration: “Deterring a conflict over Taiwan, ideally by preserving military overmatch, is a priority.” Two months later, Taiwan went entirely unmentioned in the US National Defense Strategy, as did military overmatch vis-a-vis China, giving renewed cause for concern. How to interpret these varying statements remains an open question. In both documents, the Indo-Pacific is listed as a second priority behind homeland defense and
Every analyst watching Iran’s succession crisis is asking who would replace supreme leader Ayatollah Ali Khamenei. Yet, the real question is whether China has learned enough from the Persian Gulf to survive a war over Taiwan. Beijing purchases roughly 90 percent of Iran’s exported crude — some 1.61 million barrels per day last year — and holds a US$400 billion, 25-year cooperation agreement binding it to Tehran’s stability. However, this is not simply the story of a patron protecting an investment. China has spent years engineering a sanctions-evasion architecture that was never really about Iran — it was about Taiwan. The
After “Operation Absolute Resolve” to capture former Venezuelan president Nicolas Maduro, the US joined Israel on Saturday last week in launching “Operation Epic Fury” to remove Iranian supreme leader Ayatollah Ali Khamenei and his theocratic regime leadership team. The two blitzes are widely believed to be a prelude to US President Donald Trump changing the geopolitical landscape in the Indo-Pacific region, targeting China’s rise. In the National Security Strategic report released in December last year, the Trump administration made it clear that the US would focus on “restoring American pre-eminence in the Western hemisphere,” and “competing with China economically and militarily
