Acemoglu and Johnson argue that the link between technological progress and general prosperity is not automatic. It depends on other variables, especially how well new technologies sustain the demand for labor and how much workers share the benefits of rising productivity. Having supported their argument with historical examples, they now apply it to the more recent economy, especially the period since 1980.
The “graveyard of shared prosperity”
At the height of the postwar prosperity, believers in the “productivity bandwagon” expected further technological breakthroughs to raise productivity and wages, continuing and even surpassing the postwar prosperity. Digital technologies, like the mainframe computers already in use in the 1960s, looked very promising. As the digital revolution took off, the rate of innovation soared.
“Digital technologies, even more so than electricity…are general purpose, enabling a wide range of applications.” They have the potential not only to replace human labor with smart machines, but also to complement and enhance human labor. During my university career, I used computers to enhance my teaching, research and administrative work in numerous ways, but they never replaced me in any of those roles. Many manufacturing workers weren’t so lucky, as new technologies were used more to replace labor than to augment it. As the authors put it, “Digital technologies became the graveyard of shared prosperity.” I would emphasize the word “shared” in that claim, since no one disputes that digital technologies have created great riches for some and modest gains for others.
The authors attribute much of the decline of shared prosperity to a more conservative vision of progress that developed in the 1960s and 70s and became dominant after the “Reagan revolution” of 1980. In this vision, the path to prosperity started at the top, with wealthy investors, high-profit corporations, and well-rewarded shareholders. If left alone by government, they would create more wealth and income for all. But to maximize investment, the rich needed low taxes; and to maximize profits, corporations needed low taxes, minimal regulation, and low labor costs. “Many American managers came to see labor as a cost, not as a resource…This meant reducing the amount of labor used in production through automation.”
Americans may place most of the blame for lost manufacturing jobs on foreign competitors like China, but automation is responsible for more job losses and downward mobility. While foreign workers and immigrants did take many of the of the low-wage manufacturing jobs, automation destroyed more of the jobs that had been paying good wages.
The workers who remained in manufacturing were more productive, but the demand for additional workers fell. In addition, total factor productivity grew at a much slower rate after 1980 than in the previous four decades. Median wages grew even more slowly, less than 0.45% per year.
Inequality increased in a number of ways:
[T]he share of the richest 1 percent of US households in national income rose from around 10 percent in 1980 to 19 percent in 2019…Throughout most of the twentieth century, about 67-70 percent of national income went to workers, and the rest went to capital (in the form of payments for machinery and profits). From the 1980s onward, things started getting much better for capital and much worse for workers . By 2019, labor’s share of national income had dropped to under 60 percent…
What income did go to labor was divided more unevenly across educational levels, with college-educated workers gaining some ground, while less educated workers saw actual declines in real earnings. Rather than train less educated workers, employers more often replaced them with fewer but more educated workers. Along with the destruction of manufacturing jobs came the decline of unions and the reduced power of workers to fight for good wages and job training.
The value of the five biggest corporations—Google, Facebook, Apple, Amazon and Microsoft—grew to about 20 percent of GDP, twice as much as the value of the five biggest corporations at the height of the Gilded Age in 1900.
Artificial intelligence
Acemoglu and Johnson see artificial intelligence making matters worse, since so many employers are using it to replace human labor rather than augment it. Rather than ask how machines can be useful to workers, proponents of new technologies ask how machines can equal or surpass human workers. Taken to an extreme, the goal of AI enthusiasts is to achieve a general machine intelligence that can make any decision as well as a human. From a business standpoint, it is the ultimate way of cutting labor costs, by replacing educated as well as less-educated labor.
So far, the results have been a lot of what the authors call “so-so automation,” with only modest gains in productivity. The reason, they think: “Humans are good at most of what they do, and AI-based automation is not likely to have impressive results when it simply replaces humans in tasks for which we accumulated relevant skills over centuries.”
What makes us think that the way to prosperity is to devalue the human capacities of the workers who are trying to prosper? That may generate short-term profits for the owners of the machines, but not shared and sustained prosperity. The authors warn that “infatuation with machine intelligence encourages mass-scale data collection, the disempowerment of workers and citizens, and a scramble to automate work, even when this is no more than so-so automation—meaning that it has only small productivity benefits.”
The threat to democracy
The part of the book I found most disturbing was the chapter, “Democracy Breaks.” It describes what some have called a new “digital dictatorship,” most evident in China. With the help of some of the world’s largest AI companies, the Chinese government has turned the data-crunching capacities of new technologies into tools of mass surveillance and control. The aim is to monitor, rate, and sanction the behavior of any citizen. Forty years after Orwell’s imaginary 1984, Big Brother is watching more efficiently than ever. Other authoritarian governments—Russia, Iran, Saudi Arabia, Hungary, and even India—are developing similar capabilities.
In the United States, “The NSA cooperated with Google, Microsoft, Facebook, Yahoo!, various other internet service providers, and telephone companies such as AT & T and Verizon to scoop up huge amounts of data about American citizens’ internet searches, online communications and phone calls.”
Digital media have also played a role in polarizing Americans and debasing civil discourse. Media companies whose business model was based on selling ads, such as Facebook, wanted to keep their users as engaged as possible. “Any messages that garnered strong emotions, including of course hate speech and provocative misinformation, were favored by the platform’s algorithms because they triggered intense engagement from thousands, sometimes hundreds of thousands, of users.”
The hope that digital media would—like the printing press of an earlier era—empower citizens and strengthen democracy has not been fulfilled. The underlying problem, according to Acemoglu and Johnson, is that technology companies prefer a more “technocratic approach, which maintains that many important decisions are too complex for regular people.” In the economy, that encourages the devaluation and replacement of human laborers and a flow of economic rewards to the rich. In government, it enables the surveillance and control of citizens and a flow of political power to authoritarian leaders.
Redirecting technology
In their final chapter, Acemoglu and Johnson describe a three-pronged formula for redirecting technology: “altering the narrative and changing norms…cultivating countervailing powers…[and] policy solutions.”
The new narrative would reject “trickle-down economics” and shift the emphasis back to shared prosperity. It would encourage decision-makers to address the wellbeing of ordinary people, instead of assuming that what’s good for corporate profits or large fortunes is good for everybody. Hopefully it would influence how business managers think and what they learn in business school.
Countervailing power against self-serving technocrats and corporations can come from many directions—government, civic organization and online communities. Now that blue-collar manufacturing workers are a smaller part of the labor force, organized labor should grow to embrace many occupations. Workers should organize on a broader level than the plant or the firm and play a major role in national politics.
Here are some of the policy changes they recommend:
- Subsidize socially beneficial technologies, especially those that augment human labor rather than replace it
- Support research on such technologies, especially in education and health care
- Break up technology companies that have become too monopolistic
- Reform tax policies that favor investments in equipment over hiring of workers
- Increase tax incentives for worker training
- Repeal the law that exempts internet platforms from any accountability for what they post
- Tax platforms that rely on advertising in favor of those with alternative revenue streams, such as subscriptions or nonprofit contributions
- Raise the minimum wage, but do not provide a Universal Basic Income
The authors regard a Universal Basic Income as “defeatist,” since it “fully buys into the vision of the business and tech elite that they are the enlightened, talented people who should generously finance the rest.” What they support instead is a new vision committed to seeing the value and productive potential in all of us and investing accordingly.
