Why We Have A Wage Inequality Problem

Wage inequality is a topic in elections around the world. What can be done to provide more income for those without jobs, and those with low wages?

Wage inequality is really a sign of a deeper problem; basically it reflects an economic system that is not growing rapidly enough to satisfy everyone. In a finite world, it is easy for an economy to grow rapidly at first. In the early days, there are enough resources, such as land, fresh water, and metals, for each person to get a reasonable-sized amount. Each would-be farmer can obtain as much land as he thinks he can work with; fresh water is readily available virtually for free; and goods made with metals, such as cars, are not expensive. There are many jobs available, and wages for most people are fairly similar.

As population grows, and as resources degrade, the situation changes. It is still possible to grow enough food, but it takes large farms, with expensive equipment (but very few actual workers) to produce that food. It is possible to produce enough water, but it takes high-tech equipment and a handful of workers who know how to use the high-tech equipment. Metals suddenly need to be lighter and stronger and have other characteristics for the high tech industry, thus requiring more advanced products. International trade becomes more important to be able to get the correct mix of materials for the advanced products needed to operate the high-tech economy.

With these changes, the economic system that previously provided many jobs for those with limited training (often providing on-the-job training, if necessary) gradually became a system that provides a relatively small number of high-paying jobs, together with many low-paying jobs. In the United States, the change started happening in 1981, and has gotten worse recently.

What Happens When An Economy Doesn’t Grow Rapidly Enough?

If an economy is growing rapidly enough, it is easy for everyone to get close to an adequate amount. The way I think of the problem is that as economic growth slows, the “overhead” grows disproportionately, taking an ever-larger share of the goods and services the economy produces. The ordinary worker (non-supervisory worker, without advanced degrees) tends to get left out. Figure 2 is my representation of the problem, if the current pattern continues into the future.

The reason for the workers’ declining share of the total is that we live in a finite world. We are using renewable resources faster than they replenish and continue to use non-renewable resources. The workarounds to fix these problems take an increasing share of the total output of the economy, leaving less for what I have called “ordinary workers.” The problems we encounter include the following:

Pollution control. Pollution sinks are already full. Continuing to use non-renewable resources (including burning fossil fuels) adds increased pollution. Workarounds have costs, and these take an increasing share of the output of the economy.

Energy used in energy production. When we started extracting energy products, the cheapest, easiest-to-extract energy products were chosen first. The energy products that are left are higher-cost to extract, and thus require a larger share of the goods the economy produces for extraction.

Water, metals, and soil workarounds. These suffer from deteriorating quantity and quality, leading to the need for workarounds such as desalination plants, deeper mines, and more irrigated land. All of these take an increasingly large share of the output of the economy.

Interest and dividends. Capital goods tend to be purchased through debt or sales of stock. Either way, interest payments and dividends must be made, leaving less for workers.

Increasing hierarchy. Companies need to be larger in size to purchase and manage all of the capital goods needed to work around shortages. High pay for supervisors reduces funds available to pay lower-ranking employees.

Government funding and pensions. Government programs grow in size in good times, but are hard to cut back in hard times. Pensions, both government and private, are a particular problem because the number of elderly people tends to grow.

It should be no surprise that this type of continuing pattern of eroding wages for ordinary workers leads to great instability. If nothing else, workers become increasingly disillusioned and want to change or overthrow the government.

It might be noted that globalization also plays a role in this shift toward lower wages for ordinary workers. Part of the reason for globalization is simply to work around the problems listed above. For example, if pollution becomes more of a problem, globalization allows pollution to be shifted to countries that do not try to mitigate the problem. Globalization also allows businesses to work around rising the rising cost of oil production; production can be shifted to countries that instead emphasized coal in their energy mix, with much lower energy used in energy production. With increased globalization, people who are primarily selling the value of their own labor find that wages do not keep up with the rising cost of living.
