Eight Centuries of Increasing Food Abundance in England: Summary

Basic food commodities have become far cheaper, and virtually all workers have reaped the benefits.

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. My recent series of articles looked at the affordability of food relative to wages in England between the 13th century and the present. It covered dairy (milk, butter, and cheese), meat (pork, mutton, and beef), baking (flour, sugar, and eggs), and grains (wheat, rice and oats).

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 calculated the number of hours that someone must work to earn enough money to buy a particular food item.

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

Figure 1: Compound annual growth rates for skilled and unskilled workers

For unskilled laborers, the compound annual growth rate of all the items analyzed increased from 0.19 percent on average before the 1860s (going back to 1200s for some commodities) to 1.38 percent since the 1860s.

Similarly, for skilled laborers, the compound annual growth rate increased from 0.17 percent on average before the 1860s (going back to 1200s for some commodities) to 1.37 percent since the 1860s.

Over the course of this series, we showed how workers have benefited hugely from the growth in wages since the Industrial Revolution. However, this growth has accelerated since the end of World War II. When basic food commodities became cheaper, all workers saw the benefits.

Many compare their circumstances in the present to others who are relatively better off. However, compared to almost any period in history, everyone has benefited as basic commodities became far more affordable.

UK Food Inflation Falls Despite Energy Shock

“Britain's food industry warned in February that soaring energy costs following U.S. and Israeli strikes on Iran could push food price inflation towards 10% by Christmas.

Six months later, food ​inflation has instead fallen to a near two-year low, as fierce supermarket competition, consumers' resistance to further price rises and better hedging by suppliers helped absorb ‌the shock.”

Time Pricing the Fourth of July Cookout

Independence and abundance.

Summary: The dollar price of a traditional Fourth of July cookout has increased since 2016, but rising wages have more than offset those higher prices. As a result, Americans spend less time working to earn this year’s Independence Day meal than they did a decade ago. Measured in time rather than dollars, the data show that abundance has continued to grow as the population has increased.


Every year, the American Farm Bureau Federation estimates the cost of a traditional Independence Day cookout. The basket includes summer cookout staples such as cheeseburgers, chicken breasts, pork chops, potato chips, pork and beans, fresh strawberries, homemade potato salad ingredients, fresh-squeezed lemonade ingredients, chocolate chip cookies, and ice cream.

Since 2016, the dollar cost of this basket has risen 30.3 percent, from $56.67 to $73.82. At first glance, that suggests celebrating the Fourth of July has become significantly more expensive.

But money prices tell only half of the story. The real question is not how many dollars the meal costs, but how much time people must work to earn those dollars. Since 2016, blue-collar worker hourly earnings increased 50.4 percent, from $21.48 to $32.31 per hour.

Because wages rose faster than prices, the time price of the cookout actually fell 13.4 percent—from 2.64 hours of work in 2016 to just 2.28 hours today, a savings of 21 minutes.

Another way to measure progress is to ask: How much more does the same hour of work buy? We call this the abundance multiplier. Compared with 2016, the same amount of work today buys 15.5 percent more.

America added 22 million people between 2016 and today, a population increase of 6.8 percent. Yet abundance didn’t merely keep pace with population—it grew 2.28 times as fast. Every 1 percent increase in people produced a 2.28 percent increase in cookout abundance. That’s the signature of superabundance: on average, every additional person contributes more than they consume. Even though there are 22 million more of us, we’ll actually spend 7.5 percent less time working as a country to pay for our celebration compared with 2016.

Americans may spend more dollars, but they spend less of their lives earning this year’s Independence Day feast.

Government money printing during the COVID-19 pandemic did cause a temporary spike, but we have returned to the long-term trend of decreasing time prices and increasing abundance.

This year saw a slight reversal. Compared with the record-low time price in 2025, food prices increased 4.1 percent while blue-collar hourly earnings rose 3.5 percent. As a result, the time price of the cookout edged up by just 0.5 percent—less than one minute of additional work. Even after that small increase, the Independence Day cookout remains substantially more affordable in time than it was a decade ago.

Berries Are Probably Not Making Parents Go Broke

“The Washington Post recently ran a fun, data-filled article on berry consumption and parenting. Lots of good tidbits in the article, including that Americans eat a lot more berries than in the recent past, and that a lot of the availability is thanks to foreign trade and imports. But despite being somewhat light-hearted, the article does seem very negative, especially in the title and introduction, about how parents are spending a lot of money on berries…

Relative to median wages, berries of all kinds are now more affordable than a decade ago. Parents may still feel squeezed by all the berries their kids are eating, but in terms of affordability and share of the family budget, there is probably no need for a Berry Panic.”

Time Pricing Big Macs Around the World

Even if a Big Mac is more expensive in money, it can be less expensive in time.

Summary: Big Mac prices across countries can be better understood by measuring them in terms of time rather than money—specifically, how long people must work to afford one. Comparing time prices reveals meaningful differences in wages and productivity that aren’t obvious from currency values alone.


McDonald’s operates in over 100 countries worldwide. Since 1986, The Economist magazine has published the Big Mac Index, built on the theory of purchasing power parity (PPP)—the idea that exchange rates should equalize the price of an identical basket of goods across countries. The following shows the dollar price of a Big Mac in each country, sorted by price:

But we can go one step further.

Instead of comparing currencies, we can compare time.

We start with the nominal price of a Big Mac in each country, converted to U.S. dollars, and then compare it to average hourly earnings. Since average hourly earnings data are not available for all countries, GDP per capita divided by annual hours worked serves as a reasonable proxy for relative wages between countries.

This transforms the question from “What does it cost?” to “How long do you have to work to get it?” A Big Mac can be more expensive in money but less expensive in time, depending on where you live.

A Big Mac in Taiwan costs only $2.38, compared to $7.99 in Switzerland, but after adjusting for hourly earnings, the time prices are very similar. In Pakistan, a Big Mac costs $3.77, but hourly earnings are $0.86, putting the time price at 4.4 hours. In Denmark, the price is $5.49, but hourly earnings are $57.60, so the time price is under six minutes. For the time it takes a worker in Pakistan to earn enough to buy one Big Mac, workers in Denmark can buy more than 46.

The Big Mac doesn’t just measure currencies; it measures the spread of knowledge.

What looks like inequality in dollars is often a difference in productivity, learning, and institutional capacity. The real divide is not between rich countries and poor countries—it is between places where knowledge compounds and places where it is constrained.

When a sandwich falls from four hours of work to four minutes, something profound has happened—not to the burger, but to the growth and sharing of knowledge.

The story of abundance is not written in dollars. It is written in time.
