Ghana’s Poverty Eases as Nutrition and Education Improve

“Ghana said it had made progress in curbing poverty amid an improvement in households’ conditions of nutrition and education, although inequality remained a persistent problem.

A multidimensional poverty index for the West African nation declined to 21.9% at the end of the third quarter of last year from 24.9% in the final quarter of 2024, Ghana Statistical Service said in a report on Wednesday…

The measure tracks worsening states of living, employment, health and education using 13 indicators.”

GLP-1 Adoption Is Changing Consumer Food Demand

“We examine how consumers modify their food purchases after adopting appetite-suppressing GLP-1 receptor agonists, such as Ozempic and Wegovy. Using survey responses on medication adoption linked to transaction data from a representative U.S. household panel, we document the prevalence, motivations, and demographic patterns of GLP-1 adoption. Households with at least one GLP-1 user reduce grocery spending by 5.3% within six months of adoption, with higher-income households reducing spending by 8.2%. While most food categories see spending declines, the largest reductions are concentrated in calorie-dense, processed categories, including a 10.1% decline in savory snacks. In contrast, a small set of categories show directionally positive changes, with yogurt experiencing the only statistically significant increase. We also find an 8.0% decline in spending at fast-food chains, coffee shops, and limited-service restaurants. These food demand adjustments persist through the first year of medication use, though with some attenuation after six months.”

Wheat Superabundance Proves Malthus Wrong

Compared to 1960, we can grow 250 percent more wheat on 9 percent more land, at an 85.7 percent lower time price.

Summary: For centuries, people feared that population growth would outstrip food supply, leading to famine and collapse. Yet wheat tells a different story: production has soared, yields have multiplied, and the cost in human effort has plummeted. Despite wars, droughts, and disruptions, innovation and open markets have made wheat more abundant than ever.


The Reverend Thomas Malthus (1766–1834) got it backwards. In his 1798 Essay on Population he warned that “the power of population is indefinitely greater than the power in the earth to produce subsistence for man. Population, when unchecked, increases in a geometrical ratio. Subsistence increases only in an arithmetical ratio.”

Malthus even added, with no small dose of condescension, that “a slight acquaintance with numbers will shew the immensity of the first power in comparison of the second.”

When Malthus published his essay, the world’s population hovered around 1 billion. By 1960 it had reached 3 billion. Today it stands at roughly 8.2 billion. And yet, instead of mass starvation, food production has outpaced population growth. Consider wheat.

According to the US Department of Agriculture, since 1960 wheat production has surged by 250 percent, while the world’s population grew by only 171 percent. For every 1 percent increase in population, wheat production rose by 1.46 percent. Even more remarkable, this bounty came from just 9 percent more arable land. Wheat yields—the amount harvested per acre—have soared by 271 percent.

But what about the time price? Glad you asked. Since 1960, the time price of wheat has fallen by 85.7 percent.

Put differently, the time it took to earn the money to buy a single bushel of wheat now buys almost seven bushels.

Yes, there have been moments when wheat prices spiked—due to droughts, wars, and politics. Yet with fewer conflicts, relentless innovation, and open markets, wheat has only grown more abundant. If Reverend Malthus could see our world today, I suspect he’d be relieved—and perhaps even delighted—that human ingenuity proved him to be so spectacularly wrong.

McDonald’s Abundance Serves the World

The premier American brand has sold a trillion burgers.

Summary: With plausibly up to a trillion burgers sold worldwide, McDonald’s has become one of the most recognizable symbols of abundance and convenience. Its cheeseburger now takes far less work time to afford than in the past, reflecting broad gains in prosperity. McDonald’s has grown into a cultural touchstone, serving communities across the globe.


In 1948, McDonald’s offered nine items on its menu. This helped simplify operations and lower costs. McDonald’s stopped officially counting its hamburger sales after surpassing 100 billion burgers in 1994. However, based on recent estimates of roughly 75 burgers sold every second—or approximately 2.36 billion per year—the total number of burgers sold by McDonald’s is likely in the hundreds of billions, with some sources suggesting McDonald’s has already sold its trillionth burger.

My favorite McDonald’s item is the cheeseburger. It’s been my top choice since 1973, when McDonald’s first came to my hometown. This product will provide you with 300 calories, 15 grams of protein, 31 grams of carbohydrates, 13 grams of fat, and 720 milligrams of sodium. I think it’s delicious and a great food value.

In 1948, entry-level workers were earning around 66 cents an hour. A 19 cent cheeseburger would cost them around 17.4 minutes. Today they’re $1.99 and entry-level food service workers are earning $18.67 an hour, putting the time price at 6.4 minutes. The time price has dropped by 63 percent: You get 2.7 cheeseburgers today for the time price of one in 1948.

Today, with over 41,800 stores in 118 countries and global sales of $130 billion, chances are, wherever you go in the world you can find the Golden Arches calling you. Approximately 93 percent of the restaurants are owned and operated by independent franchisees, which has made many of them millionaires.

Chris Arnade has written extensively about how important McDonald’s is to American culture. He has a PhD in physics from Johns Hopkins University and worked for 20 years as a trader at an elite Wall Street bank before leaving in 2012 to become a photojournalist. His writings include many beautiful photographs that reveal the central role McDonald’s plays in many communities. Please take a few minutes to enjoy his work here.

Writing this has made me hungry. Time to add to that trillion burger count.
