Why American Workers Are Losing Their Share of Economic Growth: The Impact of AI and Automation

Introduction

The United States has one of the world's largest and most technologically advanced economies. Businesses continue to invest in new technologies, companies are expanding their operations, and artificial intelligence is changing how industries produce goods and deliver services. However, an important question is emerging: Are ordinary American workers benefiting from this economic progress as much as business owners and investors?

Recent economic data suggests that workers are receiving a smaller proportion of the value generated by the American business sector. Although overall economic activity can increase, wages and employee compensation do not necessarily grow at the same pace.

This issue has attracted attention because of the rapid development of artificial intelligence (AI), workplace automation, changing business practices, and the declining influence of organized labor.

According to the US Bureau of Labor Statistics (BLS), the labor share of output reached 52.8% in the second quarter of 2026, its lowest recorded level in a data series beginning in 1947.

This development raises important questions about income distribution, financial security, economic inequality, and the future relationship between technology and employment.

1. Understanding Why Workers Are Receiving a Smaller Share

To understand this economic trend, it is important to know what economists mean by the term "labor share of income."

Labor share measures the percentage of economic output that goes to workers in the form of compensation. This includes more than regular salaries. It also accounts for benefits, employer contributions to retirement plans, and other forms of employee compensation.

For example, imagine a business produces $1 million worth of economic output. If $550,000 is attributed to labor compensation, the labor share would be 55%.

A lower labor share means that compensation represents a smaller proportion of the measured output. It does not automatically mean that every employee has experienced a pay cut. Workers' actual earnings can increase while their share of total production decreases if business output grows faster than compensation.

This distinction is essential when evaluating the American economy.

2. Official Data Shows a Historic Decline

The latest available Bureau of Labor Statistics figures provide an important indication of the changing relationship between workers and economic production.

In the second quarter of 2026, the labor share of output in the nonfarm business sector stood at 52.8%. The BLS identified this as the lowest level in its historical series, which begins in the first quarter of 1947.

For comparison, the measure was generally between 60% and 66% during much of the postwar period.

The longer-term pattern indicates that the labor share experienced fluctuations over several decades, followed by a more sustained decline after the beginning of the 21st century.

Several economic developments may help explain this movement, including changes in technology, business organization, productivity, industry competition, and workers' negotiating power.

However, the labor-share statistic should not be confused with the percentage of national wealth owned by employees or the amount of money received by an individual household. It measures a specific relationship between compensation and economic output.

3. Artificial Intelligence Is Changing the Relationship Between Work and Profits

Artificial intelligence is becoming an increasingly important part of modern business operations. Companies are adopting AI systems to process information, analyze data, communicate with customers, automate routine activities, and improve production processes.

These technologies can help businesses complete certain tasks more quickly and potentially reduce operating costs.

For example, a company that previously required several employees to perform repetitive administrative activities may now use software to automate some of those processes. The business may be able to increase production without expanding its workforce at the same rate.

This creates an important economic question: Who receives the financial benefits of improved productivity?

If a company generates more revenue through technology but does not increase employee compensation proportionately, a larger portion of the resulting economic gains may remain with business owners and investors.

Nevertheless, AI should not be treated as the only explanation for declining labor income. The current data does not establish that artificial intelligence alone caused the historic decline.

Its long-term influence will depend on how businesses implement the technology, whether new jobs are created, how workers adapt, and whether productivity improvements lead to higher wages.

4. Other Economic Factors Behind the Declining Labor Share

Technology is only one part of the story. Several other structural changes may also influence how income is distributed between workers and businesses.

A. Automation and technological investment

Automation has gradually transformed manufacturing, transportation, retail, financial services, and many other industries.

Machines and computer systems can perform certain activities that previously required human labor. This can increase productivity and reduce the amount of labor needed for a particular level of production.

Although automation can create new employment opportunities, the benefits may not be distributed equally across occupations and income groups.

B. Increasing market concentration

When a small number of large companies control significant portions of an industry, competition may become weaker.

Businesses with strong market positions can sometimes maintain higher profit margins and exercise greater influence over suppliers and employees.

If workers have fewer alternative employers, their ability to negotiate better salaries and working conditions may also be affected.

C. Weaker collective bargaining power

Labor unions and collective bargaining organizations have historically played an important role in negotiating wages, benefits, and workplace protections.

When union representation declines, or workers have limited negotiating opportunities, employees may find it harder to secure a share of productivity gains that matches their contributions.

The relationship between union strength and labor compensation varies across industries, but bargaining power remains an important factor in discussions about income distribution.

D. Globalization and international competition

Globalization has allowed companies to move production, purchase materials, and provide services across international markets.

Businesses may relocate certain operations to countries with lower labor costs or use international suppliers to reduce expenses.

These decisions can benefit companies and consumers by lowering production costs, but they can also put pressure on wages and employment opportunities in some domestic industries.

5. Why Economists Disagree About Measuring Workers' Income Share

Although the BLS figure highlights a substantial decline, economists do not all interpret the number in the same way.

One reason is that economic measurements depend on the definitions, calculations, and accounting methods being used.

Some analysts argue that conventional gross-income measurements can exaggerate the extent to which income has shifted away from workers.

For example, business owners operating through pass-through entities may receive income that is classified differently from traditional employee wages. Some of this income can represent compensation for the owner's work rather than a pure return on invested capital.

Depreciation is another important consideration. Businesses regularly invest in computers, software, machinery, buildings, and other assets. These assets lose value through use and aging. Different treatments of depreciation can change the measured division between labor income and capital income.

The treatment of stock-based compensation and other employee incentives can also influence calculations.

The Tax Foundation has argued that a net-income approach provides a different picture from the commonly cited gross labor-share statistic. Its analysis emphasizes that depreciation and taxes should be considered when interpreting how much income actually accrues to capital.

This disagreement does not mean that the BLS data is incorrect. Rather, it demonstrates why economists should examine the methodology before drawing conclusions about the entire economy.

6. The Impact on American Households and Consumers

A declining labor share can have consequences beyond the workplace.

Workers depend on salaries and benefits to pay for housing, transportation, healthcare, education, food, and other essential expenses.

When compensation fails to keep pace with productivity and economic growth, households may find it difficult to improve their financial position.

Several potential consequences deserve attention.

Pressure on household purchasing power:

If wages do not keep up with living costs, families may reduce discretionary spending or rely more heavily on credit.

Growing income inequality:

If a greater proportion of economic gains goes to owners of capital, investors, and highly compensated executives, the gap between different income groups may widen.

Changes in consumer confidence:

People may feel economically insecure even when headline economic indicators suggest that businesses are performing well.

Reduced opportunities for wealth building:

Workers who receive limited financial benefits from economic expansion may find it harder to save, invest, purchase property, or prepare for retirement.

These outcomes are not automatic consequences of every decline in labor share. They depend on wage growth, inflation, taxes, household wealth, public policy, and other economic conditions.

7. Could the Labor Share Fall Below 50%?

Some economists have expressed concern that the labor share could continue declining if existing structural pressures remain in place.

Artificial intelligence, automation, corporate investment, and changes in employment relationships could influence future compensation patterns.

However, a projection that the labor share may fall below 50% should be treated as a forecast rather than an established outcome.

Several developments could change the direction of the trend.

For example, increased competition between employers could encourage higher wages. New industries could create employment opportunities. Workers with specialized technical skills could benefit from rising demand, while changes in tax policy and labor regulations could influence income distribution.

The future will depend on how businesses, employees, policymakers, and educational institutions respond to technological and economic changes.

8. What Can Be Done to Ensure Workers Benefit From Economic Growth?

Addressing the gap between productivity and compensation requires a combination of business decisions, workforce development, and public policy.

Invest in education and technical skills

Workers need opportunities to develop skills that remain valuable as technology changes. Training in digital systems, data analysis, technical maintenance, communication, and specialized professional fields can help employees adapt.

Encourage fair compensation practices

Businesses can consider how productivity improvements translate into wages, bonuses, employee benefits, and opportunities for career development.

Support healthy competition

Effective competition can encourage businesses to improve products and services while giving employees more opportunities to seek better employment conditions.

Improve access to AI education

Rather than treating artificial intelligence only as a threat, educational institutions and employers can help workers understand and use these tools effectively.

Examine economic policy carefully

Policymakers can review taxation, workforce protections, training programs, and labor-market regulations to determine whether economic growth is creating opportunities across different income groups.

The objective should not be to prevent technological progress. It should be to ensure that productivity improvements create meaningful benefits for the wider population.

Conclusion

The declining labor share of American economic output is an important development that deserves careful attention. The latest BLS figure of 52.8% in the second quarter of 2026 highlights how much the relationship between workers and economic production has changed over time.

Artificial intelligence and automation may influence this trend, but they are not the only contributing factors. Business concentration, globalization, labor bargaining power, accounting methods, and structural changes in the economy also matter.

The central challenge for the United States is to ensure that economic progress does not benefit only those who own businesses, technology, and financial assets.

A strong economy should create opportunities for employees as well as investors. Ultimately, the success of technological innovation should be measured not only by how much companies produce, but also by how effectively its benefits improve people's lives.
