Inequality on the Horizon of Need

by J. Bradford DeLong

J. Bradford DeLong, a former Assistant US Treasury Secretary in the Clinton administration, is Professor of Economics at the University of California at Berkeley.

BERKELEY – By any economic measure, we are living in disappointing times. In the United States, 7.2% of the normal productive labor currently stands idle, while the employment gap in Europe is rising and due to exceed that of the US by the end of the year. So it is important to step back and remind ourselves that the “lost decade” that we are currently suffering is not our long-run economic destiny.

As Paul Krugman recently reminded us, John Maynard Keynes perhaps put it best: 

“This is a nightmare, which will pass away with the morning. For the resources of nature and men’s devices are just as fertile and productive as they were. The rate of our progress towards solving the material problems of life is not less rapid. We are as capable as before of affording for everyone a high standard of life – high, I mean, compared with, say, 20 years ago – and will soon learn to afford a standard higher still. We were not previously deceived. But today we have involved ourselves in a colossal muddle, having blundered in the control of a delicate machine, the working of which we do not understand. The result is that our possibilities of wealth may run to waste for a time.”

But what is our long-run economic destiny? Keynes looked forward to a time, perhaps 2050, when everyone (in England, at least) would be able to have the lifestyle of a Keynes. And, because he imagined that no sane person could want more of the necessities, conveniences, and luxuries of life than a Keynes had, the economic problem would be solved. 

We are wiser – and perhaps sadder – than Keynes. We know that we want hip replacements and heart transplants and fertility treatment and cheap air travel and central heating and broadband Internet and exclusive beachfront access. Already nearly everybody in the North Atlantic region has enough food to avoid hunger, enough clothing to stay warm, enough shelter to remain dry. And yet we want more, feel resentful when we do not get it, and are self-aware enough to know that luxuries turn into conveniences, and then into necessities – and that we are very good at inventing new luxuries after which to strive.

So the economic problem will certainly be with us for a long time yet. But at least we can count on being able to generate a relatively egalitarian middle-class society as we collectively slouch toward our consumerist utopia, right? 

It was Karl Smith of the University of North Carolina who explained to me that this was likely to be wrong. The long post-Industrial Revolution boom, which carried unskilled workers’ wages to previously unheard-of heights – keeping them within shouting (or at least dreaming) distance of the lifestyles of the rich and famous – is not necessarily a good guide to what will come next.

To create wealth, you need ideas about how to shape matter and energy, additional energy itself to carry out the shaping, and instrumentalities to control the shaping as it is accomplished. The Industrial Revolution brought ideas and energy to the table, but human brains remained the only effective instrumentalities of control. As ideas and energy became cheap, the human brains that were their complements became valuable. 

But, as we move into a future of artificial intelligence that observers like Kevin Drum expect (or even of the artificial moronity that is already clearly at hand), and into a future of biotechnology that grows itself as biological systems do, won’t human brains cease to be the only valuable instrumentalities of control?

It is not necessarily the case that “unskilled” workers’ standards of living will fall in absolute terms: the same factors that make human brains less valuable may well be working equally effectively to reduce the costs of life’s necessities, conveniences, and luxuries. But wealth is likely to flow to the owners of productive – or perhaps fashionable – ideas, and to owners of things that can be imitated only with great difficulty and high cost, even with dirt-cheap instrumentalities of control, dirt-cheap energy, and plentiful ideas. 

The lesson is clear: the market is not guaranteed by nature to produce a long-run future characterized by a reasonable degree of wealth inequality and relative poverty. Unless and until we recognize this fully, we will remain at the mercy of Keynes’s poorly understood “delicate machine.”

EXTRACT: "The new report on 2020 by the International Renewable Energy Agency reveals that the world’s renewable energy generation capacity increased by an astonishing 10.3% in 2020 despite the global economic slowdown during the coronavirus pandemic." .... "In 2020, the global net increase in renewables was 261 gigawatts (GW). That is the nameplate capacity of some 300 nuclear power plants! There are actually only 440 nuclear power plants in the whole world, with a generation capacity of 390 gigwatts. So let’s just underline this point. The world put in 2/3s as much renewable energy in one year as is produced by all the existing nuclear plants!"

EXTRACT: "When we examined the development of nations worldwide since 1820, we found that among rich Western countries like the United States, the Netherlands and France, improvements in income, education, safety and health tracked or even outpaced rising gross domestic product for over a century. But in the 1950s, even as economic growth accelerated after World War II, well-being in these countries lagged.

EXTRACT: "Some presidents indulge in the “Mount Rushmore syndrome” making an obvious effort to achieve greatness. Normally soft-spoken and apparently modest Biden is making his own bid for immortality."
Apr 9th 2021
EXTRACT: "New ways of thinking about the role of government are as important as new priorities. Many commentators have framed Biden’s infrastructure plan as a return to big government. But the package is spread over eight years, will raise public spending by only one percentage point of GDP, and is projected to pay for itself eventually. A boost in public investment in infrastructure, the green transition, and job creation is long overdue."
Apr 7th 2021
EXTRACT: " One can, and perhaps should, take the optimistic view that moral panics in the US blow over; reason will once again prevail. It could be that the Biden era will take the sting out of Trumpism, and the tolerance for which American intellectual life has often been admired will be reinvigorated. This might even happen while the noxious effects of American influence still rage in other countries. For the sake of America and the world, one can only hope it happens soon.  "

EXTRACT: "By refusing (despite having some good reasons) to end electoral gerrymandering, Chief Justice John G. Roberts, Jr., has directly enabled the paralyzing hyper-partisanship that reached its nadir during Donald Trump’s presidency. By striking down all limits on corporate spending on political campaigns in the infamous 2010 Citizens United decision, he has helped to entrench dark money in US politics. And by gutting the 1965 Voting Rights Act in Shelby County v. Holder, Roberts has facilitated the racist voter-suppression tactics now being pursued in many Republican-controlled states."

EXTRACT: "the UK’s tough choices accumulate, and the problems lurking around the corner look menacing. Britain will have to make the best of Brexit. But it will be a long, hard struggle, all the more so with an evasive fabulist in charge."
Mar 15th 2021
EXTRACT: "Over the years, the approach of most American policymakers toward the Israeli-Palestinian conflict has been Israel-centric with near total disregard for the suffering endured by the Palestinian people. The architects of policy in successive US administrations have discussed the conflict as if the fate of only one party (Israel) really mattered. Israelis were treated as full human beings with hopes and fears, while Palestinians were reduced to a problem that needed to be solved so that Israelis could live in peace and security.  ..... It is not just that Israelis and Palestinians haven’t been viewed with an equal measure of concern. It’s worse than that. It appears that Palestinians were judged as less ​human than Israelis, and were, therefore, not entitled to make demands to have their rights recognized and protected."

EXTRACTS: "XThere’s a global shortage in semiconductors, and it’s becoming increasingly serious." ...... "The automotive sector has been worst affected by the drought, in an era where microchips now form the backbone of most cars. Ford is predicting a 20% slump in production and Tesla shut down its model 3 assembly line for two weeks. In the UK, Honda was forced to temporarily shut its plant as well." ..... " As much as 70% of the world’s semiconductors are manufactured by just two companies, Taiwan Semiconductor (TSMC) and Samsung."

EXTRACT: "Back in 1992, Lawrence H. Summers, then the chief economist at the World Bank, and I warned that pushing the US Federal Reserve’s annual inflation target down from 4% to 2% risked causing big problems. Not only was the 4% target not producing any discontent, but a 2% target would increase the risk of the Fed’s interest-rate policy hitting the zero lower bound. Our objections went unheeded. Fed Chair Alan Greenspan reduced the inflation target to 2%, and we have been paying for it ever since. I have long thought that many of our economic problems would go away if we could rejigger asset markets in such a way as to make a 5% federal funds rate consistent with full employment in the late stage of a business cycle."
Mar 2nd 2021
EXTRACT: "Under these conditions, the Fed is probably worried that markets will instantly crash if it takes away the punch bowl. And with the increase in public and private debt preventing the eventual monetary normalization, the likelihood of stagflation in the medium term – and a hard landing for asset markets and economies – continues to increase."
Mar 1st 2021
EXTRACT: "Massive fiscal and monetary stimulus programs in the United States and other advanced economies are fueling a raging debate about whether higher inflation could be just around the corner. Ten-year US Treasury yields and mortgage rates are already climbing in anticipation that the US Federal Reserve – the de facto global central bank – will be forced to hike rates, potentially bursting asset-price bubbles around the world. But while markets are probably overstating short-term inflation risks for 2021, they do not yet fully appreciate the longer-term dangers."
Feb 28th 2021
EXTRACT: "To be sure, calls to “build back better” from the pandemic imply some awareness of the need for systemic change. But the transformation we need extends beyond constructing modern infrastructure or unlocking private investment in any one country. We need to re-orient – indeed, re-invent – global politics, so that countries can cooperate far more effectively in creating a better world."
Feb 23rd 2021
EXTRACT: "So, notwithstanding the predictable release of pent-up demand for consumer durables, face-to-face services show clear evidence – in terms of both consumer demand and employment – of permanent scarring. Consequently, with the snapback of pent-up demand for durables nearing its point of exhaustion, the recovery of the post-pandemic US economy is likely to fall well short of vaccine development’s “warp speed.” "
Feb 20th 2021
EXTRACT: "Human rights abuses under Erdogan are beyond the pale of inhumanity and moral decadence. The list of Erdogan’s violations and cruelty is too long to numerate. The detention and horrifying torture of thousands of innocent people for months and at times for years, without being charged, is hard to fathom. Many prisoners are left languishing in dark cells, often in solitary confinement. The detention of tens of thousands of men and hundreds of women, many with their children, especially following the 2016 failed coup, has become common. It is calculated to inflict horrendous pain and suffering to bring the prisoners to the breaking point, so that they confess to crimes they have never committed."

EXTRACT: "Global regulators will no doubt be concerned about a potential volatility spillover from digital asset prices into traditional capital markets. They may not permit what could quickly amount to effective proxy approval by the back door for companies holding large proportions of a volatile asset on their balance sheets."
Feb 11th 2021
EXTRACT: "Since Russians began protesting opposition leader Alexei Navalny’s imprisonment, the security forces have apparently had carte blanche to arrest demonstrators – and they have done so by the thousands. If Russians so much as honk their car horns in solidarity with the protesters, they risk personal repercussions. The official response to the protests goes beyond the Kremlin’s past repression. It is war."

EXTRACT: ".......like Biden, Roosevelt was certainly no revolutionary. His task was to save American capitalism. He was a repairer, a fixer. The New Deal was achieved not because of Roosevelt’s genius or heroism, but because enough people trusted him to act in good faith. That is precisely what people are expecting from Biden, too. He must save US democracy from the ravages of a political crisis. To do so, he must reestablish trust in the system. He has promised to make his country less polarized, and to restore civility and truth to political discourse. In this endeavor, his lack of charisma may turn out to be his greatest strength. For all that he lacks in grandeur, he makes up for by exuding an air of decency."
Feb 2nd 2021
EXTRACT: "Europe must not lose sight of the long game, which inevitably will center on China, not Russia or relations with post-Brexit Britain. China is already establishing a presence in Iran, and demonstrating that it has the capital, know-how, and technology to project power and influence beyond its borders. Should it succeed in turning the Belt and Road Initiative into a line of geopolitical stepping-stones, it might soon emerge at Europe’s southeastern border in a form that no one in the EU foresaw."
