Why Workers’ Share of Income Is Falling Before the AI Boom

The Shrinking Slice Workers Get The Labor Share of Income and AI Productivity

Imagine a pie that represents all the money earned in a country. This pie is divided into two main slices: one for the workers who create goods and services, and another for the owners of the businesses and tools (like factories, machines, and software) used to make them. The “labor share of income” is simply the percentage of that total pie that goes to workers as wages and salaries. Recently, this slice has been shrinking, hitting a record low in many places. This trend has economists and everyday people asking: what’s happening, and why does it matter?

How the Labor Share of Income Works

At its core, the labor share of income is a way to see how the rewards of economic activity are distributed. When a company makes a product or provides a service, the money it earns is used to pay for various costs, including wages for its employees, materials, rent, and taxes. What’s left over is profit, which goes to the owners or shareholders.

Let’s say a small bakery bakes bread. The total money the bakery earns from selling bread in a month is its “income.” This income is used to pay:

Wages: To the bakers and cashiers.
Costs: For flour, yeast, electricity, rent for the shop.
Profit: For the owner.

If the total income is $10,000, and $6,000 goes to wages and $4,000 goes to costs and profit, the labor share of income for that bakery would be 60% ($6,000 / $10,000). If wages went up to $7,000, the labor share would rise to 70%. If technology allowed the owner to bake more bread with fewer bakers, and profits increased significantly, the labor share could fall.

Why the Labor Share of Income Matters to You

Understanding the labor share of income is crucial because it directly impacts many aspects of our financial lives and the broader economy.

For individuals, a lower labor share of income often means that wages aren’t keeping pace with the overall growth of the economy. This can contribute to “wage stagnation,” where your paycheck doesn’t increase much year after year, even if the company you work for is doing well or becoming more efficient. This directly affects your ability to save, invest, and achieve financial goals. It can also exacerbate “economic inequality,” the gap between the rich and the poor, if a larger portion of the economic pie goes to those who own capital (businesses and assets) rather than those who provide labor.

On a larger economic scale, a declining labor share can influence consumer spending, as people with less disposable income buy fewer goods and services. It can also signal shifts in economic power between labor and capital, potentially leading to different investment patterns and influencing inflation. When workers have less purchasing power, demand for goods and services might soften, which can affect business growth and job creation.

The Trend of a Shrinking Labor Share

Historically, the labor share of income has fluctuated. However, in many developed economies, there has been a noticeable downward trend over the past few decades. While it’s a complex phenomenon with many contributing factors, a recent point of focus is the role of technological advancement, particularly the rise of “AI productivity.”

Gregory Daco, Chief Economist at EY-Parthenon, has provided insights into this trend. He notes that even before the widespread adoption of advanced AI, productivity growth was occurring. Productivity is essentially how much economic output (goods and services) can be produced with a given amount of input (like labor and capital). When productivity rises, the economy can produce more. The question is, who benefits from this increased output?

Daco’s analysis suggests that in recent years, much of the “productivity gains” have not translated into higher wages for workers. Instead, they have disproportionately benefited the owners of capital. This means that as technology made businesses more efficient, the profits from that efficiency went more to the owners of the technology and the companies, and less to the employees whose labor was being complemented or, in some cases, replaced by that technology.

The Future Impact of Automation and AI

The increasing sophistication of automation and Artificial Intelligence (AI) is a significant driver behind the current interest in the labor share of income. These technologies can perform tasks previously done by humans, sometimes more efficiently and at a lower cost.

Think about it this way:

Traditional Automation: Imagine robots on an assembly line assembling cars. These robots increase efficiency and output.
AI Automation: Now consider AI that can write reports, analyze complex data, or even provide customer service. This type of AI can potentially impact a much wider range of jobs, including white-collar professions.

When AI and automation become more capable, there’s a risk of “technological unemployment,” where fewer human workers are needed to produce the same amount or even more output. If businesses adopt these technologies rapidly and the gains in productivity are captured primarily by the owners of the technology, the labor share of income could continue to decline. Gregory Daco’s research points to this ongoing shift, where technological advancements contribute to higher overall economic output but can lead to a smaller slice of that pie for the average worker if not managed carefully. This situation can also impact “workforce economics” broadly, as the demand for certain skills changes.

Practical Implications for Your Financial Thinking

Given the trend, how should you think about this in your financial life?

Focus on Skill Development: In a world where automation is evolving, investing in your own skills and education becomes even more important. Skills that are complementary to technology or that AI cannot easily replicate (like creativity, complex problem-solving, and emotional intelligence) may command higher wages.
Understand Your Value: It’s helpful to understand how your role contributes to your employer’s productivity and profitability. This knowledge can be valuable in salary negotiations.
Diversify Income Streams: For some, relying solely on a single wage might become riskier. Exploring side hustles or investments can provide additional financial security.
Be a Savvy Investor: If you own stocks or other assets, you are part of the “capital share.” Understanding these trends can inform your investment decisions, but remember that investing always involves risk.

A common misconception is that technological advancement is always bad for workers. Historically, technology has also created new jobs and industries. However, the speed and nature of AI advancements raise new questions about the pace of job displacement versus job creation and the distribution of economic gains.

Connections to Other Financial Concepts

Understanding the “labor share of income” is deeply intertwined with several other key economic and financial concepts:

Capital Share of Income: This is the other side of the coin, representing the portion of national income that goes to owners of capital (profits, rent, interest). A falling labor share typically means a rising capital share.
Economic Inequality: As mentioned, a widening gap between the labor share and capital share can directly lead to greater economic inequality.
Wage Stagnation: This is often a consequence of a declining labor share, where workers’ pay doesn’t keep up with inflation or economic growth.
Productivity Gains: These are the engine of economic growth. How the benefits of these gains are distributed is the crucial question for the labor share.
Automation Impact: The increasing use of machines and AI in production processes is a primary driver of changes in the labor share.
Technological Unemployment: This is the potential downside of automation, where jobs are eliminated faster than new ones are created.

Understanding the dynamics of the labor share of income helps illuminate how the economy grows and who benefits from that growth, offering a clearer picture of “workforce economics.”

Common Questions About the Labor Share of Income

What is the labor share of income?

The labor share of income is the percentage of a country’s total economic output that is paid to workers as wages and salaries. It shows how the rewards of economic activity are split between labor and capital.

Why has the labor share of income hit a record low?

While multiple factors contribute, recent trends point to technological advancements, including automation and AI, driving productivity gains. These gains have, in many cases, disproportionately benefited capital owners rather than leading to significant wage increases for workers.

How does AI productivity affect the labor share of income?

AI productivity can increase the efficiency of businesses. If the cost savings and increased output from AI lead to higher profits for owners without corresponding wage increases for employees, the labor share of income will likely decrease.

What is the “capital share” of income?

The capital share of income is the portion of a country’s total economic output that goes to the owners of capital, such as profits for business owners, rental income, and interest payments. A declining labor share often corresponds to a rising capital share.

Can individuals directly influence the labor share of income?

Individuals cannot directly control the national labor share of income. However, through collective action like unionization, advocating for policies that support workers, and investing in their own skills, individuals can indirectly influence labor market dynamics and the distribution of economic gains.

How does this affect economic inequality?

When the labor share of income falls and the capital share rises, it can widen the gap between those who earn their income from work and those who earn income from owning assets, thus increasing economic inequality.

What are the risks associated with a low labor share of income?

A low labor share can lead to wage stagnation for many workers, reduced consumer spending, and increased economic inequality. It might also create social and political instability if a large segment of the population feels left behind by economic progress.
