AI cannot make the planet bigger. The population that can have a sustainable universal high standard of living will have to be much smaller than today’s, whether there is a lot or only a little work left for people to do. #Population #FutureOfWork #BasicIncome
China, Japan, and Korea all had increases in GDP in 2025, even though they all had decreases in their populations. This is how to become prosperous while saving the environment.#Sustainability #Population
In our crowded, stressed world, couples with few or no children are being sensible, and their leaders urging them to have more are not. #population
When population is allowed to shrink, before long there is an abundance of affordable housing. Homelessness ends. #population #Homeless
Bannon & Sanders are right: Immigration not answer for skilled-worker shortages. Higher pay for nurses, engineers + more (or bigger) medical schools is the answer, and will help & encourage young Americans. #Immigration
Housing crisis: Once our population stabilizes or starts shrinking, it will be easier to have housing for everyone.
The dock workers are wrong. Mechanization, replacing workers with machines is true progress. More leisure time, less need for population increase (babies or immigrants). Enables transition to smaller population thriving comfortably, sustainably.
People in poor countries multiply, and then cause climate change in 2 more ways: They cut down their forests, and they migrate to rich countries, where they pollute and consume like others there. #ClimateJustice #population
The Economist Tokyo bureau chief warns East Asian countries their percentage of the global economy will shrink along with their population. Do they care? To attain universal high standards of living, populations must shrink. Shift from growth models to shrink models. #population
Per Economist editor, Germany needs more immigrants for aging population and shrinking workforce. But Germany is overpopulated. For longterm prosperity, it should shrink. Population growth means more workers, but also more demand for work. It’s a pyramid scheme. #population
The Intelligence podcast (June 7): The Economist economics editor, Henry Curr, dismisses concerns about population growth; humans can solve the environmental problems. (Aren’t we doing great? - deforestation, mass extinctions, global warming …). #population
The Intelligence podcast (June 7): The Economist economics editor, Henry Curr, says: Population growth drives economic growth; it is bad that world population is on track to stop growing. (He should admit that the world economy is a pyramid scheme.) #population
French workers should accept a later retirement age temporarily to facilitate a demographic transition to a stable (and perhaps, at some point, for a limited time, a shrinking) population size that will enable sustainable comfort and prosperity in the long run. #population
Our capitalist system is a giant Ponzi scheme, which relies on an ever-growing number of poor at the bottom. That’s why Elon Musk and other tycoons don’t want population to stop growing. #population #capitalism #capitalismiscancer
Tennessee lawmakers got one wrong and one right: Drag shows are appropriate for any audience, but sex-change procedures cause irreversible damage, and should not be performed on kids. #transgender
Per-capita economic growth leads to prosperity. Zero economic growth with a shrinking population will do it. Don’t worry about Japan or China. #population
Banning females from schools and workplaces is a tragedy for Afghanistan and a blow to our planet. It will not help lower the country’s fertility rate, which is the highest outside of Africa. More environmental damage. More hunger. #population
Pakistan not to blame for climate change, floods? Population 1.5 x Russia’s & growing (many have emigrated to rich countries, & pollute just as others there). Only 2% forest. Rich nations exploited & must pay poor – including for family planning & reforestation. #Climatechange
OK, Trump and Giuliani are nasty and vicious. But how come no one calls out someone who says the Constitution was "divinely inspired?" Encouraging that crazy notion is dangerous and an obstacle to progress. #SeparationOfChurchAndState
