“The world has made spectacular progress in every single measure of human well-being,” is the cheery synopsis of the new book, “Enlightenment NOW: The Case for Reason, Science, Humanism, and Progress “ (p. 52) by Harvard University’s Johnston Family Professor of Psychology, Steven Pinker.
Important aspects of this “spectacular progress,” he says, are world-wide increasing life expectancy, declining maternal mortality and declining birth rates (pp. 53-57, 125-26, 273).
Unless I missed it in the 453-page book, however, Pinker does not grapple with the problems created by lower birth rates coupled with longer life spans. Examples of such problems are seen in Iowa and Minnesota in the U.S. and Brazil, Japan and Cuba.
For the Wall Street Journal, Iowa is an example of “a problem playing out in many parts of the Midwest, a region with lower unemployment and higher job-opening rates than the rest of the country. Employers, especially in more rural areas, are finding that there are just too few workers.” In fact, if “every unemployed person in the Midwest was placed into an open job, there would still be more than 180,000 unfilled positions, according to the most recent Labor Department data. The 12-state region is the only area of the country where job openings outnumber out-of-work job seekers.”
This problem is associated with low birth rate coupled with and an outflow of people. A net 1.3 million people living in the Midwest in 2010 had left by the middle of last year, according to census data. The area also attracts fewer immigrants than the rest of the country.”
A similar problem exists in Minnesota. Last month, its unemployment rate dropped to 3.2%, compared with 4.1% nationally. This has made it difficult for “manufacturers, construction firms and repair-service firms to fill job vacancies and replace departing retirees try to meet the need for more employees, some firms, “employer associations and cooperating unions are working jointly to expand the labor pool.”
For the tech sector of the economy, last year Minnesota added 3,500 jobs, up 1.4% to 250,000 and constituting around 8% of the state’s total work force. And there is demand for even more such workers.
Minnesota’s need for immigrants is especially pronounced in the assisted-care industry. In late March the Trump Administration announced that it was ending, effective March 31, 2019, the Deferred Enforcement Departure program for certain Liberians in the U.S. One of the largest communities of Liberians lives in Minnesota and at least 1,000 are members of a local union that provides workers for assisted-care facilities.
“Retirement outlays already eat up 43% of Brazil’s national budget, and health care about 7%, while two expenditures that are critical to economic development—education and infrastructure—claim only about 3% each.” Its “social security system’s revenue shortfall widens each year as the worker-to-pensioner ratio shrinks.” This problem is exasperated by decisions last century to grant pensions to millions of peasants and informal workers who hadn’t paid [into the pension system]. . . . Rural workers paid about $3 billion in social-security taxes for the 12 months through September 2017, while rural retirees drew about $36 billion in benefits.”
The solutions are obvious. “They can raise the minimum retirement age, increase the number of years that workers must pay into the system, or reduce payouts. The bad news is that such measures tend to repel voters.”
Brazil is not alone.
Japan has a very low birth rate, very high life expectancy and very low immigration. As a result, it has an aging, declining population, which should lead to declining economic and political importance in the world.
Cuba has the same sort of problems. It has a declining birth rate associated with readily available abortion services, longer life-spans associated with good health care and many younger people leaving the island to find greater economic opportunities elsewhere.
More generally, “throughout Latin America and Asia, decades of falling birth rates and growing life expectancies have produced more retirees with fewer workers to underwrite their care. For government policy makers, this means challenges as burgeoning pension and health costs leave less money for economic development.”
“The United Nations projects that by 2050, the number of potential workers per retiree in upper-middle-income developing countries such as Brazil will tumble from the 2015 figure of seven to just 2.5.”
“Credit-rating firms are getting anxious. Standard & Poors estimates that unless there are major changes to publicly funded pension and health-care systems, population aging will help drive net government debt in the biggest emerging economies to extraordinary levels—307% of gross domestic product in Brazil, 274% in China, 262% in Russia and 341% in Saudi Arabia by 2050.”
The U.S. now has a fertility rate below the replacement rate. It, therefore, needs foreign immigrants to sustain population growth, especially in the rural parts of states like Iowa and Minnesota.
Such immigration also would provide workers to pay into the Social Security trust fund and thereby help to finance the increasing number of older Americans who now draw benefits from that fund and who face rising costs of medical care.
