What Is Economic Inequality? Definition, Causes, and Key Statistics

What Is Economic Inequality?

Economic inequality refers to disparities among individuals' incomes and wealth. And those differences can be great. Forbes counted a record 2,781 billionaires in the world as of 2024. Meanwhile, the World Bank estimates that more than 700 million people globally are living on less than $2.15 per day. That's actually a big improvement from 1990, when over 1.9 billion people lived in extreme poverty and the world had only 269 billionaires.

Some will look at these numbers as evidence that a rising tide lifts all boats. Over the past 30 years, global wealth has increased; overall, living standards have improved. And others will look at these numbers and think it's inexcusable that anyone lives in poverty when the world's billionaires are worth a combined $14.2 trillion. Of course, both statements can be simultaneously true.

Disparities like these—and the ones many people see in their everyday lives, where people experiencing homelessness or housing insecurity live in tent cities only miles from fancy condos—give rise to questions about economic inequality. What is it? How and why does it happen? Is it the natural order of things, or is the system rigged? Should attempts be made to make things more equal—for instance, by increasing taxes on higher incomes, as Sweden has? And is the pandemic going to make this inequality worse?

We don't have the answers. The causes of economic inequality are multifarious, and our society hasn't reached a consensus on what, if anything, to do about it, with political deadlock keeping things as status quo for the time being. What we can offer is some background and insight on the state of economic inequality in this country.

Understanding Economic Inequality

The essence of economic equality is how much money the least well off make compared to the most well off—and how wealth is distributed in a society. What assets do people own to tide them over during difficult times and to help them invest in new opportunities? These differences matter for several reasons.

Let's look first at the psychological aspect of economic inequality. We all compare ourselves to others. How satisfied we are with our income or net worth depends not just on how low or high those figures are, nor purely on what we can buy with our incomes or how comfortable our wealth makes us.

Instead, our satisfaction depends, in part, on how our income and wealth compare to that of others: our neighbors, colleagues, friends, siblings, classmates, and bosses. Let's take an accountant we'll call Lorenzo as an example. Lorenzo may be perfectly happy earning $70,000 a year in his accounting job—but only until he learns that his colleague and fellow accountant Sebastian is earning $80,000. The inequality feels unfair. It makes him unhappy; maybe even angry.

Lorenzo confronts Sebastian, asking him what he's doing to earn an extra $10k a year. He points out that they both have the same amount of experience, they started working at the firm at around the same time, and they do the same job.

In response, Sebastian says that it's a bigger deal that their CEO earns $60 million. Plus, their friend Marco, who works in customer service through a contractor their firm hires, only makes $20 an hour and doesn't get the same benefits as they do. No health insurance. No 401(k). Only 10 days of paid time off per year, and he has to choose between using those for vacation, personal time, or sick leave.

Is Economic Equality Desirable?

Lorenzo has an explanation for Marco's position and pay. Marco didn't go to college, whereas Lorenzo and Sebastian worked hard in high school and got into good universities. On top of that, they both became certified public accountants, which meant putting in a lot of extra work, taking extra exams, and spending a lot of money to get their certifications. It wouldn't make sense for Marco to earn $75,000. He didn't do any of that. That's the way the system works.

Most Americans would agree. They would say that even though Lorenzo and Sebastian are both single and Marco is supporting his partner and two children—so, arguably, Marco needs the higher income more than Lorenzo and Sebastian do—they don't like the idea of "from each according to his ability, to each according to his needs." That's the communist credo, and communism, after taking hold in the Soviet Union in 1917, led to millions of government-ordered executions, mass starvation, war, and widespread human misery. (However, there are those who would argue that the problem is not the communist philosophy itself, but its historical implementation under brutal dictators.)

Back to our accountants. Lorenzo doesn't think it's fair to give $15,000 of his $70,000 salary to Marco so they can each earn an equal $55,000 a year. Sebastian doesn't want to give up that kind of money, either. Although he doesn't have a partner or kids, he does have a mortgage to pay, and he wants to go back to school to earn an MBA. That's not cheap. He doesn't want to support someone else's kids. If he were only going to earn $55,000 a year, he wouldn't have bothered to become a CPA.

How Does Economic Inequality Happen?

We've seen that one reason economic inequality is a problem is that we compare ourselves to others. We feel bad when we find out that other people have more than we do, especially when we're similar to those people. People need incentives to work hard, and they feel they deserve to keep what they earn. They also believe in meritocracy, the idea that people advance in wealth and status through hard work, not through privilege. But how would Lorenzo and Sebastian feel if they learned more about Marco's life story?

Marco grew up in a semi-rural community. The schools he attended were slightly below average, and he didn't have any choice about where to get his education. His dad stocked shelves at the local grocery store. His mom was a restaurant server. Neither of his parents finished high school. They couldn't help him with his homework. They often worked nights and weekends. Marco's grandparents watched him during those times, and he played with the neighborhood kids. In high school, he got a job as a busboy at the restaurant where his mom worked. His friends were good kids, but none of them ever talked about going to college. Most adults in their lives were not college graduates. No one expected Marco or his friends to go to college or enter a white-collar profession.

Lorenzo and Sebastian both grew up in cities. Sebastian's parents lived in an upper-middle-class neighborhood with great public schools. Lorenzo's parents took advantage of a school choice program to get him into better schools. Both boys' teachers saw promise in them and encouraged them to take advanced classes. They didn't always get straight As, but they did get good enough grades to get into name-brand colleges. Plus, all their friends were going to college. Their teachers expected them to go and helped them prepare.

For these three men, inequality of opportunity led to where they are today. None of them did anything wrong. Nor did their parents do anything wrong. But Sebastian benefited from the intergenerational wealth that allowed him to grow up in a nice area with quality schools. Lorenzo benefited from having access to those schools and growing up alongside kids like Sebastian whose parents expected their children to attend college and pursue corporate careers with good pay and benefits. Marco had none of these advantages.

This example is just one way economic inequality can happen. However, it happens, the life consequences are substantial.

How the COVID-19 Pandemic Has Exposed Economic Inequality

The everyday threat of COVID-19—a highly contagious, sometimes deadly virus that no one is known to have lasting immunity to—has made more people aware of the economic inequalities in our society. Examples are accumulating: There's the legacy of abuse and marginalization of Latinx Americans, black Americans, and Native Americans, all groups getting infected and dying from the virus at rates far higher than whites. And there's the low pay received by workers in demanding and dangerous jobs. Meat processors and slaughterers, who earn a mean hourly wage of $15.00 as of May 2020 ($31,210 annually), according to the U.S. Bureau of Labor Statistics, have been disproportionately infected by COVID-19 outbreaks at work.

On March 19, 2020, Christopher Krebs, director of the U.S. Department of Homeland Security's Cybersecurity and Infrastructure Security Agency, issued a memorandum identifying the "essential critical infrastructure workers," commonly referred to as "essential workers," whose jobs are key for protecting public health and safety and economic and national security. "The industries they support represent, but are not necessarily limited to, medical and healthcare, telecommunications, information technology systems, defense, food and agriculture, transportation and logistics, energy, water and wastewater, law enforcement, and public works," the memo states.

This list is not a mandate, but it provides advice to the states on who should keep going to work and who should stay home to help prevent the spread of the disease. The goal? To "flatten the curve," to avoid overwhelming the healthcare system such that sick people cannot receive potentially life-saving treatment. The memo also encourages remote work where possible and provides strategies to reduce the spread of disease among those who cannot work remotely.

Economic Inequality and Health

Following the release of a memo from Homeland Security regarding essential workers and COVID, there's been evidence that many employers have not provided adequate protection to keep essential workers from catching and spreading COVID-19. In part, the problem can be attributed to the global lack of pandemic preparedness and, according to national press reports, massive shortages in personal protective equipment, even for medical providers. But what is also evident is that economic inequality has made a bad situation much worse for many workers.

Some have continued going to their high-risk jobs because they feel they have no choice: Their families rely on their wages. A 62-year-old California woman told the Los Angeles Times how she kept going to her $13.58-an-hour job washing laundry at a nursing home even though her husband, who has underlying heart problems, didn't want her to. She said she had to support her family; they all got the virus.

Situations like these have led some to say that those deemed essential workers are really being treated as expendable workers. Hazard pay, where it's been offered, has been deemed insufficient; it may also soon prove temporary. Some employers, perhaps most notoriously airlines, have even forbidden their workers to wear face masks and kept them in the dark about on-the-job exposure to the virus.

Some people have gone to work with COVID-19 symptoms because their employers don't provide the pay, benefits, or sick leave they need to take time off and get healthcare. Millions have been forced into unemployment by stay-at-home orders, so while they may be safer from the coronavirus, they don't have money to pay their bills unless they have robust emergency savings, and most people don't. The unemployed also may not have health insurance to get treatment if they get sick, since affordable, high-quality health insurance in the United States is often tied to employment, even with the Affordable Care Act (ACA).

Let's return to the story of our fictional workers. Marco, a customer service representative at an office that has closed down due to the pandemic, is technically able to work from home. But the company doesn't have enough work for all its reps because business has slowed so much. So he has been let go and is struggling to collect unemployment compensation from an overloaded system. Meanwhile, Lorenzo and Sebastian have continued to perform their well-paid accounting jobs from home. They also still have the health insurance that their employer never offered Marco because he works through a contractor and is not an employee of the firm. He does have an Affordable Care Act exchange plan, but he's not sure how he'll keep paying the premiums.

Going without health insurance is a huge risk for anyone, but it's an extra risk for Marco, who suffers from asthma. In fact, so do lots of the people he grew up with, maybe because many of their parents smoked, maybe because the outdoor air quality downwind of the chemical plant near their neighborhood was poor. Lorenzo and Sebastian didn't have these disadvantages. They've also got some luck on their side, and they don't have underlying health conditions.

This is yet another aspect of economic inequality that's become starker due to the pandemic: the higher prevalence of underlying health conditions such as asthma and high blood pressure in lower-income individuals and people of color because they are marginalized their entire lives. These populations are at an even more elevated risk of dying in the pandemic because their underlying health conditions predispose them to adverse outcomes from COVID-19 and they're also more likely to be exposed to it at work.

Fixing Economic Inequality

Is economic inequality something we should try to fix? In the United States, this question has become a heated political issue. It encompasses issues such as progressive taxation, universal healthcare coverage, unemployment insurance, basic income, Medicaid, and COBRA health insurance. Some people think the United States should adopt more elements of the Nordic model and strengthen its social safety net. Others feel this model is too socialist and prefer a more capitalist model. They don't want to pay the higher taxes that would be required to fund more social programs, and they argue that filling the gaps through the work of private charities is a better solution.

Most people are willing to pay taxes, but they differ in how much they're willing to pay to reduce economic inequality. Lorenzo and Sebastian like to think that the taxes they're paying on the money they are still earning are helping people like Marco right now through federal and state income security programs. Some of their tax dollars also help support their grandparents through Social Security and Medicare.

In addition, Lorenzo and Sebastian are each currently donating 10% of their pay to local nonprofits that are helping people who are unemployed get through the pandemic. They feel a need to contribute to their local community since part of the reason they're able to keep working comes down to luck, and they don't think others who are out of work should suffer because of bad luck.

The Bottom Line

Economic inequality is a tricky issue. Some level of inequality may be natural. Marco didn't choose the circumstances he was born into any more than Lorenzo and Sebastian did. But societal forces may have determined the circumstances they were born into, then perpetuated their unequal circumstances, even as other forces also helped Marco get a job that pays relatively well for someone without a college degree. But then, why shouldn't Marco have had access to the same opportunities his coworkers did? The issues of fairness and equality of opportunity lie beneath the issue of economic inequality and the degree to which it's natural, inevitable, acceptable, or even desirable. It's up to each of us to decide what we want economic equality or inequality to look like, then vote and spend our dollars accordingly.
