Lesson Overview

Featured article: Centers Progress, Pt. 12: Hangzhou (Paper Money) by Chelsea Follett

Despite China having the second biggest economy in the world and being the nation with the world’s largest population today, many students know surprisingly little about the country’s history. Even students that know a bit about China have probably never heard of the city of Hangzhou, one of the ancient capitals of China and now its fourth-largest metropolitan area with a population of over 20 million.

This article will give students a glimpse into the fascinating history of Hangzhou during its “golden age” and relates many of the innovations that made the city one of the most influential centers of progress in world history. In particular, students will learn about one commercial innovation that originated in China and has now spread all over the world: paper currency.

Warm-up

Imagine that paper money, electronic payments, and credit and debit cards disappeared tomorrow. In this alternate reality, the only way to pay for things would be by using small metal coins.

How would this change affect you, your family, and your friends?

  • Take a few minutes to reflect on how life would be different if you could use only coins to make purchases.
    • How would you feel? Do you think the transition would be easy?
    • Do you think using only coins to pay for things would be an impossible task? What would be the biggest challenges for you and your family?
    • Would there be any advantages to this old style of payment?
  • Write a paragraph describing how this change would affect your life.
  • Share your paragraph with a partner. Reflect and discuss together:
    • In what ways would you and your community be worse off with only the use of coins?
    • Would you want to live this way for a day, a month, or even a year?
    • Do you think it is possible or desirable for your town or city to flourish without the use of paper money?
  • Today you will learn about the origin of paper money in China. Before we begin, answer these questions:
    • Why do you think paper money was invented in the first place? What were the advantages of paper money over the types of money used previously?
    • What technology do you think had to be developed in order for paper money to be introduced?
    • Make a prediction: Do you think paper money originated with a central government or as an innovation of private businesspeople?

Questions for reading, writing, and discussion

Read the article, and then answer the following questions:

  • What were some of the characteristics of the economy of Hangzhou during the Song dynasty? List at least three.
  • The article mentions two advantages of using paper currency over coins. What were these advantages?
  • What role does Hangzhou play in the economic life of China today? Why is it still one of the most important cities in China?
  • According to the article, at what point did Hangzhou become the most important city in China?
  • What critical piece of infrastructure first built during the 600s CE allowed Hangzhou to be connected to the cities of northern China?
  • What technological innovation allowed for the mass production of books, documents, and banknotes during the Song dynasty? Be specific. What was the critical invention devised by Bi Sheng?
  • Despite Hangzhou being forward-thinking in many respects, what notable practice now seen as inhumane and cruel towards a particular group arose during the Song Dynasty?
  • What were some of the cultural milestones of the Song dynasty in each area of achievement? How did these innovations improve the lives of many ordinary Chinese people living in cities like Hangzhou? Fill in the chart below.
What were the achievements during the Song dynasty?How were the lives of ordinary Chinese people improved as a result?

Economics
  • How did paper currency evolve? Write a short description of its origin and development from the Tang dynasty through the Song dynasty.
  • What were some of the features of the banknotes printed by the Chinese central government in Hangzhou beginning in 1265 CE? Why did the Chinese people ascribe value to this form of currency?
  • If not managed correctly, what is one of the dangers of using paper currency in an economy? What are the consequences for ordinary people of this type of fiscal mismanagement?

Extension Activity/Homework

Watch and Learn from a China Scholar

Dr. Valerie Hansen teaches Chinese history at Yale University. She is a well-known expert on one of the most famous Chinese paintings, a masterpiece known as the “Qing Ming Scroll,” which was commissioned by a Song dynasty emperor. Although the cityscape depicted in the scroll is a fictional rendition of an “ideal” Chinese urban area during the Song dynasty, it provides extensive evidence of the technological sophistication and economic innovations that were present in Hangzhou at the time. Watch the video of Dr. Hansen describing the entire scroll in detail. As you watch, find specific evidence in the scroll that exemplifies Chinese society during the Song dynasty.

Examples in the Qingming Scroll
Social organization
Politics and governance
Interactions with the environment
Cultural developments

China Nearly Reaches High-Income Status

“In July every year, the World Bank sorts countries into income groups based on their per capita gross national income (GNI) in the previous year.

In this year’s update, China was very close to entering the high-income group: its GNI per person was $14,230; just short of the World Bank’s high-income threshold of $14,375.

The chart puts this in perspective. The bars show GNI per person for countries with at least 25 million people, ordered from poorest to richest.

Beyond income, China is already comparable to high-income countries in many dimensions. Its spending on research and development as a share of GDP, for example, is higher than in many European countries. It’s also a global leader in several technology fields, including clean energy and artificial intelligence.

But in other ways, China is closer to middle-income countries. Its productivity, measured by GDP per hour worked, for example, remains much lower than in high-income countries.”

Generational Progress on Income Growth Continues in US

“Whether each generation of Americans continues to economically surpass the previous one has recently been called into question. We construct a posttax, posttransfer income measure from 1963 to 2023 based on the Current Population Survey Annual Social and Economic Supplement that allows us to consistently compare the economic well-being of five generations of Americans at ages 36–40. We find that Millennials had a real median household income that was 20% higher than that of the previous generation, a slowdown from the growth rate of the Silent Generation (36%) and Baby Boomers (26%), but similar to that of Generation X (16%). The slowdown for younger generations largely resulted from stalled growth in work hours among women. Progress for Millennials younger than 30 has also remained robust, though largely due to greater reliance on their parents. Additionally, lifetime income gains for younger generations far outweigh their higher educational costs.”

Are Americans Getting Richer? New Data Might Surprise You

Workers have proven resilient over the past decade, despite inflation and valid affordability fears.

Summary: We introduce the American Abundance Index, which measures living standards by how many hours Americans must work to afford a standard basket of goods, rather than by prices or wages alone. The index uses time prices to show that for most US workers, purchasing power has generally risen over the last two decades, even amid inflation and public pessimism.


The resilience of the American worker is one of the most underreported stories of the 2020s. From red tape to import taxes, successive governments have erected barriers to success. Yet America’s workers have persevered and figured out ways to prosper.

A new American Abundance Index illustrates this. The project from Human Progress, an arm of the Cato Institute, reveals the steady rise of the average worker’s purchasing power. The premise of the index is simple: how many hours do you need to work, compared to the month or year before, to be able to afford the “basket of goods,” which is a standard set of household items and services that comprise the Consumer Price Index used to calculate inflation.

The “time price” is how many hours of work it takes to purchase the basket of goods. The “abundance” is how much of the basket one hour of work can buy. The story told by the index is a very good one: since recordkeeping began, “abundance” for average private sector workers comes out to a net increase of 13.8 percent.

It increased the past year, too. The index shows the average private sector worker saw prices rise by 2.7 percent from December 2024 to December 2025, while their hourly wages grew by 3.8 percent. This means workers could work 1 percent less to buy the same basket of goods. Put differently, workers could afford 1 percent more stuff.

The reason for this is that earnings have continued to outpace inflation. So long as wages increase faster than inflation, the worker gets ahead. And it’s not just desk jobs that have enabled workers to purchase the same amount of goods and services for fewer hours worked. The gain for traditional “blue collar workers” is even higher: a historical net increase of 18.4 percent since 2006.

Despite workers significantly increasing their purchasing power over the past two decades, the past five years have taken a toll. The self-inflicted pain of printing vast sums of money during the pandemic sent the annualized inflation rate to over 9 percent in 2022, far outstripping raises. While inflation is now mostly under control, it has taken time for the gap between wages and inflation to settle, and workers are only now just catching up after their losses during those inflation-heavy years.

Americans continue to rank affordability as a top concern and do not believe the government is doing enough to address the cost of living. These frustrations are understandable. Prices are still rising while tariffs and uncertainty strangle businesses and push consumer confidence to a 12-year low. America’s growth and prosperity story has always been one of fits and starts, and workers are right to demand that government gets out of their way. But the new data make clear that 21st century Americans can still be content about how far they’ve come and optimistic about how far they’ve yet to go.

Introducing the American Abundance Index

American living standards are best measured in time.

We are excited to share a new tool we’ve been building at Human Progress: The American Abundance Index—an interactive dashboard that tracks US living standards while adjusting for both inflation and rising incomes.

The idea is straightforward: how many hours do you need to work to afford the same basket of goods and services? Using Bureau of Labor Statistics data, the American Abundance Index converts price and wage growth into “time prices”—the amount of work time required to buy the Consumer Price Index (CPI) basket of goods and services—and “abundance,” which is the inverse: how much of that basket one hour of work can buy. When time prices fall, abundance rises, and each hour of work goes further. That’s the measure of affordability that actually matters.

Conceptually, this work builds off of Superabundance, a book by our editor, Marian Tupy, and his coauthor and Human Progress board member, Gale Pooley. Their core argument—that abundance is best measured in time—forms the foundation of the project. The index itself was built by our Quantitative Research Associate, Jackson Vann.

Users can select multiple worker categories, compare short- and long-run trends, and even see wage growth modeled to reflect real career progression rather than freezing workers in place. All the calculations are transparent and replicable, with the full dataset and code available on GitHub.


So what does the index actually say about American standards of living?

Over the past 12 months, inflation rose 2.68 percent while hourly earnings for the average private-sector worker grew 3.76 percent. As a result, the CPI basket became 1.05 percent more abundant. Since 2006, it has become nearly 14 percent more abundant—roughly equivalent to adding an hour of purchasing power to the average workday.
