Professor Walter Scheidel examines the history of peace and economic inequality over the past 10,000 years.

What price do we pay for civilization? For Walter Scheidel, a professor of history and classics at Stanford, civilization has come at the cost of glaring economic inequality since the Stone Age. The sole exception, in his account, is widespread violence – wars, pandemics, civil unrest; only violent shocks like these have substantially reduced inequality over the millennia.

“It is almost universally true that violence has been necessary to ensure the redistribution of wealth at any point in time,” said Scheidel, summarizing the thesis of The Great Leveler: Violence and the History of Inequality from the Stone Age to the Twenty-First Century, his newly published book.

Surveying long stretches of human history, Scheidel said that “the big equalizing moments in history may not have always had the same cause, but they shared one common root: massive and violent disruptions of the established order.”

This idea is connected to Thomas Piketty’s Capital in the Twenty-First Century (2013), a New York Times bestseller Scheidel admires. Piketty found that “inequality does not go down by itself because we have economic development,” Scheidel said. “His book covers only 200 years and argues that only violent intervention can make that happen.”

But Scheidel, who has taught a freshman seminar on long-term inequality, wanted to know if this insight can be applied to all of history. He enlisted the help of Andrew Granato, a senior majoring in economics, to compile a bibliography of more than 1,000 titles. The result is a sweeping narrative about the link between inequality and peace that harkens back to the beginning of human civilization.

Formulating such a narrative is no simple task. The Great Leveler primarily relies on the published works of other historians – a challenge, in Scheidel’s view, of trying “to synthesize highly fragmented and specialized scholarship and create a single narrative.”

As an expert on ancient Rome, however, Scheidel is well aware that pre-modern sources are limited and some are invalid. His familiarity with scant ancient sources prepared him to grapple with an abundance of more reliable modern records.

“Looking at the distant past would have been more difficult for a modernist economist or historian,” said Scheidel, for whom it is “generally easier to deal with modern evidence because it is more familiar and thoroughly studied.”

A grim view

Scheidel acknowledges his pessimism about resolving inequality. “Reversing the trend toward greater concentrations of income, in the United States and across the world, might be, in fact, nearly impossible,” he said.

Among the wide variety of catastrophes that level societies, Scheidel identifies what he calls “four horsemen”: mass mobilization or state warfare, transformative revolution, state collapse and plague.

A textbook example of mass mobilization is World War II, a conflict that embroiled many developed countries and, key for Scheidel, “uniformly hugely reduced inequality.” As with Europe and Japan, he said, “in the U.S. there were massive tax increases, state intervention in the economy to support the war effort and increase output, which triggered a redistribution of resources, benefiting workers and harming the interests of the top 1 percent.”

Another “horseman” was the outbreak of the bubonic plague in 14th-century Eurasia. While war wreaks havoc on everything, a pandemic of this magnitude “kills a third of the population, but does not damage the physical infrastructure,” Scheidel said. “As a result, labor becomes scarce, wages grow and the gap between the rich and the poor narrows.”

But inequality ratcheted up the moment the plague subsided and the population began to increase. Soon, large swaths of society would see their benefits erased – a loss that in Scheidel’s account would be briefly reversed after the two world wars in the 20th century.

State collapse has also been crucial in the history of inequality. “The rich are beneficiaries of the state,” Scheidel said, adding that “if states fall apart, everybody is worse off; but the rich have more to lose. Their wealth is wiped out by the destruction of the state, such as in the fall of the Mayan civilization or Chinese dynasties.”

Is change possible?

As for whether reducing inequality will ever be possible in peacetime, Scheidel simply said, “History does not determine the future. Things can change, but change is slow.”

“Business as usual may not be enough,” he said. “We have to think harder about how to bring change in today’s world.”

A peaceful remedy to economic inequality may start with what Scheidel calls “an understanding of historical context, because simply electing the right politicians who promise that everything will be OK is a short-term view.”

For the longer term, Scheidel said, “I am not advocating war, but repeating the same old ideas ignores the lessons of history. Something truly innovative and original may have to happen in order to create lasting change.”

Space is more important than ever for the security of the United States, but it’s almost like the Wild West in terms of behavior, a top general said today.

Air Force Gen. John Hyten, commander of the U.S. Strategic Command, spoke Jan. 24 at Stanford’s Center for International Security and Cooperation. His talk was titled, “U.S. Strategic Command Perspectives on Deterrence and Assurance.”

Hyten said, “Space is fundamental to every single military operation that occurs on the planet today.” He added that “there is no such thing as a war in space,” because it would affect all realms of human existence, due to the satellite systems. Hyten advocates “strategic deterrence” and “norms of behavior” across space as well as land, water and cyberspace.

Otherwise, rivals like China and Russia will only threaten U.S. interests in space and wreak havoc for humanity below, he said. Most of contemporary life depends on systems connected to space.

Hyten also addressed other topics, including recent proposals by some to upgrade the country’s missile defense systems.

“You just don’t snap your fingers and build a state-of-the-art anything overnight,” Hyten said, adding that he has not yet spoken to Trump administration officials about the issue. “We need a powerful military,” but a severe budget crunch makes “reasonable solutions” more likely than expensive and unrealistic ones.

On the upgrade front, Hyten said he favors a long-range strike missile system to replace existing cruise missiles; a better air-to-air missile for the Air Force; and an improved missile defense ground base interceptor.

‘Critically dependent’

From satellites to global-positioning systems (GPS), space has transformed human life – and the military – in the 21st century, Hyten said. In terms of defining "space," the U.S. designates people who travel above an altitude of 50 miles as astronauts.

As the commander of the U.S. Strategic Command, Hyten oversees the control of U.S. strategic forces, providing options for the president and secretary of defense. In particular, this command is charged with space operations (such as military satellites), information operations (such as information warfare), missile defense, global command and control, intelligence, surveillance, and reconnaissance, global strike and strategic deterrence (the U.S. nuclear arsenal), and combating weapons of mass destruction.

Hyten explained that every drone, fighter jet, bomber, ship and soldier is “critically dependent” on space to conduct their own operations. All cell phones use space, and the GPS command systems overall are managed at Strategic Command, he said.

“No soldier has to worry about what’s over the next hill,” he said, describing GPS capabilities, which have fundamentally transformed humanity’s way of life.

Space needs to be available for exploration, he said.

“I watch what goes on in space, and I worry about us destroying that environment for future generations.” He said that too many drifting objects and debris exist – about 22,000 right now. A recent Chinese satellite interception created a couple thousand more debris objects that now circle about the Earth at various altitudes and pose the risk of striking satellites.

“We track every object in space” now, Hyten said, urging “international norms of behavior in space.”

He added, “We have to deter bad behavior on space. We have to deter war in space. It’s bad for everybody. We could trash that forever.”

But now rivals like China and Russia are building weapons to deploy in the lower levels of space. “How do we prevent this? It’s bigger than a space problem,” he said.

Deterring conflict in the cyber, nuclear and space realms is the strategic deterrence goal of the 21st century, Hyten said.

“The best way to prevent war is to be prepared for war,” he said.

Hyten believes the U.S. needs a fundamentally different debate about deterrence. And it all starts with nuclear weapons.

“In my deepest heart, I wish I didn’t have to worry about nuclear weapons,” he said. Hyten described his job as “pretty sobering, it’s not easy.”

But he also noted the mass violence of the world prior to 1945 when the first atomic bomb was used. Roughly 80 million people died from 1939 to 1945 during World War II. Consider that in the 10-plus years of the Vietnam War, 58,000 Americans were killed. That’s equivalent to two days of deaths in WWII, he said.

In a world without nuclear weapons, a rise in conventional warfare would produce great numbers of mass casualties, Hyten said. About war, he said, “Once you see it up close, no human will ever want to experience it.”

Though America has “crazy enemies” right now, in many ways the world is more safe than during WWII, Hyten said. The irony is that nuclear weapons deterrence has kept us from the type of mass killings known in events like WWII. But the U.S. must know how to use its nuclear deterrence effectively.

Looking ahead, Hyten said the U.S. needs to think about space as a potential war environment. An attack in space might not mean a response in space, but on the Earth.

Hyten describes space as the domain that people look up at it and still dream about. “I love to look at the stars,” but said he wants to make sure he’s not looking up at junk orbiting in the atmosphere.

‘Space geek’

Hyten has served in the Air Force for 35 years. He originally wanted to be an astronaut, but his eyesight was too bad. He got a waiver, and graduated Harvard in 1981 with an engineering degree on a ROTC scholarship. He entered the Air Force thinking he would only do four years. But then he had a close-up view of what a young Air Force officer could find in the last frontier of space as satellites and military space science were booming.

“God, I love space,” he said.

In introducing Hyten, Amy Zegart, co-director of CISAC, described him as a person of unwavering dedication and profound insights who understands the gravity of situations. “A self-described space geek,” she said.

Hyten lauded CISAC for its research and educational work on national security, and said he enjoyed being around people willing to test out new ideas and discuss potential solutions for vexing problems.

Earlier in the day on campus, Hyten met with William J. Perry, a former U.S. Secretary of Defense and senior fellow at CISAC; George Shultz, a former U.S. Secretary of Defense and senior fellow at the Hoover Institution; and Condoleezza Rice, a senior fellow at the Freeman Spogli Institute for International Studies and Hoover Institution.

General Hyten was nominated for reassignment to head the U.S. Strategic Command on Sept. 8, 2016. He commanded Air Force Space Command from 2014 to 2016.

The Trump administration’s reinstatement of a policy that bans U.S. foreign aid to agencies that provide abortion counseling abroad was a predictable move that could have unintended consequences, Stanford researchers say.

The move freezes funding to nongovernmental organizations that provide abortion services or discuss abortions as a legitimate  family-planning option. It revives what is known as the “Mexico City Policy,” so called because it was announced by President Regan in 1984 during a U.N. population conference in Mexico City. It’s a highly partisan policy, which has been implemented under Republican administrations and suspended by Democratic presidents.

From that standpoint, the move to revive the policy was no surprise, said Grant Miller, PhD, an associate professor of medicine at Stanford and core faculty member at Stanford Health Policy. But Miller’s research has shown that the policy actually appears to have the unintended effect of increasing, not decreasing, abortions in the developing world.

“The bottom line is that it doesn’t matter what you think about abortion and the morality and ethics of it,” Miller told me. “I don’t think either side of the disagreement would think a good policy is one that leads to an increase in abortions. Neither side wants to see more abortions.”

In 2011, Miller published a study with Eran Bendavid, MD, on the impact of the policy between 1994 and 2008 in sub-Saharan Africa, a region in which family planning services are heavily financed by U.S. foreign aid. Family planning agencies provide a range of family planning services, including contraception, so when their funding is cut, the availability of contraception declines, said Bendavid, the study’s lead author and another faculty member at Stanford Health Policy. This results in declining use of safe contraception and an increase in abortion rates, the researchers found.

“Sure enough, where you see this relative decline in use of contraception is where you see this uptick in abortion,” said Bendavid, an assistant professor of medicine. “Our theory of what is underlying this is this notion that when women have more restricted access to modern contraception, they rely on abortion. If the intention was to curb abortion, then what we observe is that cutting support to family planning organizations led to the  opposite effect.”

Miller followed that up with another study published in 2016 that focused on Nepal during the period when the government legalized abortion, making it more widely available. The policy change gave him the opportunity to test the idea of abortion and contraception as substitutes — i.e. that use of one method to limit family size reduces use of the other. In fact, as the number of abortions rose, use of contraception declined, he found.

“What is remarkable is that this is clear evidence on this interchangeable use that women make in use of contraceptives and abortion services,” Miller said.

In other words, women are trying to control the number of children they have and will use one or the other, depending in part upon what is most available. “If contraception is available, they won’t have to resort to abortion,” Bendavid said.

He said these results have subsequently been corroborated in other studies in sub-Saharan Africa.
