Eight Centuries of Increasing Food Abundance in England: Baking

Baking products have become much more abundant for skilled and unskilled workers alike.

Summary: The historical analysis of food affordability in England reveals a fascinating trend of growing abundance of baking goods. Over the centuries, the time and effort required to acquire items like eggs, flour, and sugar have significantly decreased, making them more accessible for both skilled and unskilled workers. This article sheds light on the remarkable progress in food availability and its impact on living standards over time.


Human progress is often incremental, but many positive trends have become clearly visible over time. One of these trends is the growing abundance of food. This series of articles for HumanProgress.org will look at the affordability of food relative to wages in England between the 13th century and the present.  

Professor Gregory Clark of the University of California, Davis, has conducted extensive research into the economic history of England. As part of his research into the condition of the working class in England, Clark has developed an extensive data set containing nominal prices of goods, and nominal wages of skilled and unskilled workers in England between the 13th and 19th centuries. Note: Clark assumes a 10-hour workday before 1720.

Using the concept of time prices developed by Marian L. Tupy and Gale L. Pooley, we can calculate the number of hours of work that someone must work to earn enough money to buy a particular food item.  

In this analysis, Clark’s nominal prices of food items serve as the nominator, and nominal hourly wages, which come from Clark and from the UK’s Office of National Statistics’ Annual Survey of Hours and Earnings, serve as the denominator.

Figure 1: Food abundance from the perspective of unskilled workers in England, hours of labor

As we can see in Figure 1, a dozen eggs fell from 1.72 hours of labor in the 1400s to 0.25 hours of labor in 2022. A pound of flour fell from 0.75 hours of labor to 0.02 hours, and a pound of sugar fell from 19.78 hours of labor to 0.03 hours.

Figure 2: Food abundance from the perspective of unskilled workers in England, per hour of labor

As we can see in Figure 2, an hour of work bought 7 eggs for an unskilled worker in 1410. That rose to 47.7 eggs in 2022. Instead of 0.79 pounds of flour, an unskilled worker got 50.46 pounds. Instead of 0.03 pounds of sugar, he or she got 29.94 pounds.

That means that unskilled workers earned 6.8 times as many eggs per hour in 2022 compared to the 1400s. For every pound of flour in the 1400s, an unskilled worker earned 64 pounds in 2022. Instead of 1 pound of sugar, he or she got 1001 pounds.

Figure 3: Food abundance from the perspective of skilled workers in England, hours of labor

As we can see in Figure 3, for a skilled worker, a dozen eggs fell from 1.02 hours of labor in the 1400s to 0.2 hours of labor in 2022. A pound of flour fell from 0.75 hours of labor to 0.02 hours, and a pound of sugar fell from 19.78 hours of labor to 0.03 hours.

Figure 4: Food abundance from the perspective of skilled workers in England, per hour of labor

As we can see in Figure 4, an hour of work bought 11.8 eggs for a skilled worker in the 1400s. That rose to 60.9 eggs in 2022. Instead of 1.34 pounds of flour, a skilled worker got 64.5 pounds. Instead of 0.05 pounds of sugar, he or she got 38.27 pounds.

Put differently, skilled workers earned 5.2 times as many eggs per hour in 2022 compared to the 1400s. For every pound of flour in the 1400s, a skilled worker got 48.2 pounds in 2022. Instead of 1 pound of sugar, he or she got 757 pounds. 

Clearly, baking products became much more abundant for both skilled and unskilled workers. Moreover, note that the time price differential between unskilled laborers and skilled tradesmen has shrunk. For example, to afford a dozen eggs in the 1400s, an unskilled worker would have to work 1.72 hours compared to 1.02 hours for a skilled worker, a difference of over 40 minutes. However, in 2022, an unskilled worker would work 15 minutes to afford a dozen, and a skilled worker would work 12 minutes, a difference of only 3 minutes. Put differently, unskilled workers have become better-off relative to their more-skilled compatriots.

Finally, the rate of growth in abundance has clearly accelerated over the last 200 years. Whereas the rate of growth in the abundance of eggs, flour, and sugar grew at a compounded annual rate of about 0.28% between 1410 and 1865 for an unskilled worker, it grew 1.97% between 1865 and 2022. Similarly, for a skilled worker, the compound annual growth rate increased from 0.26% before 1865 to 1.86% afterwards. In fact, between 1410 and 1865, eggs became relatively more expensive for both unskilled and skilled workers. Since the mid-1800s, the rate of growth of wages relative to prices has increased dramatically.

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.”

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.

From Muscle to Mind: Earn More with Fewer Calories and Fewer Deaths

Office workers use 77.8 percent less energy and experience a 95.3 percent lower fatality rate than construction workers.

Summary: Work has changed dramatically over time, shifting significantly from physical to mental labor. Today, office jobs demand far less physical energy and carry far lower risks of injury or death compared to physically demanding trades. This transition shows how progress has allowed us to create more value with less strain on our bodies—and with far greater safety than workers of the past could have imagined.


Economist George Gilder points out that using blue-collar hourly wage rates to calculate time prices underestimates the gains we’re enjoying in an economy that’s no longer driven by muscle but by mind. Knowledge workers earn more in an hour, consume fewer calories, and risk far less death or injury than other workers. In other words, they do far more with far less. This is the true compounding of progress—and we can see it mapped on a single chart.

Calories Per Hour of Work

I asked several AI models about the number of calories per hour that different kinds of work require and this is what I got:

The energy demands of physical work versus knowledge work reveals a dramatic difference in caloric expenditure. Workers in physically demanding jobs burn significantly more calories than do their office counterparts:

High-energy physical work:

  • Construction tasks such as masonry or hanging sheetrock: 400–500 calories per hour (equivalent to running or high-intensity aerobics)
  • Heavy lifting and transport: 285–300 calories per hour for a 170-pound worker

Moderate physical work:

  • Manufacturing: 228 calories per hour (men), 180 calories per hour (women)

Office work:

  • Standing desk: 186 calories per hour for a 170-pound person
  • Sitting desk work: 100 calories per hour

As we transition from working with atoms to working with knowledge our bodies require a lot less energy to perform that work. Moving from construction work to sitting at a desk in an office requires 77.8 percent fewer calories per hour. Put another way, the calories needed to fuel one construction worker can power 4.5 office workers. The result is an economic system that creates more value with less resource consumption.

Fatal work injury rate

The Bureau of Labor Statistics reports on fatalities on the job:

Farming, fishing, and forestry are the most dangerous professions at 24.4 fatal injuries, with transportation and material moving at 13.6, and construction and extraction at 12.9. Office and administrative support are the least risky professions at 0.6. Farmers, fishermen, and loggers are more than 40 times likely than an office worker to be killed on the job. Moving from construction work to sitting at a desk in an office reduces the risk of a work fatality by 95.3 percent. Adjusted for population size, construction workers experience a work-related fatality rate more than 21 times higher than that of office workers.

And it was much worse in the past—something that we tend to forget when looking at present statistics. In 1900, deaths in the mining and oil extractions fields (lumped under mining) was estimated at 333 per 100,000 workers and remained that high through the 1920s. We can hardly comprehend just how good we’ve got it now.

Calorie-fatality index

If we combine these two factors into a calorie-fatality index and compare the construction and office industries, we note that office work is 99 percent lower than construction work on the index. Moving from blue-collar construction work to an office job indicates an overall improvement factor of 96.75 (or 9,575 percent) on the calorie-fatality index.

Breastfeeding in Indonesia on the Rise

“In Indonesia … The rate of exclusive breastfeeding among infants under six months has steadily increased, rising from 52% in 2017 to 66.4% in 2024. However, many infants are not exclusively breastfed for the full six months – the duration required to achieve the full health benefits.”
