There are different causes for economic inequality and poverty, including:
- Inequality of opportunities
- Different levels of resource ownership
- Different levels of human capital
- Discrimination (gender, race and others)
- Unequal status and power
- Government tax and benefits policies
- Globalisation and technological change
- Market-based supply side policies
Inequality of opportunities
Inequality of opportunities
Differences in life opportunities due to factors beyond an individual’s control.
- The concept of inequality of opportunity assumes that true equity would exist if everyone started life under identical conditions with equal access to resources: if all had equal opportunities.
- In such a scenario, individual outcomes (wealth, income, success...) would be determined solely by factors within a person’s control, like effort and hard work.
- In reality, this ideal is unattainable: factors such as socioeconomic background, systemic discrimination, and geographical disparities mean that opportunities are not evenly distributed, making this assumption unrealistic.
Examples of factors that may affect the opportunities of an individual:
- Parents' education.
- Parents' income.
- Country of birth.
- Race.
- Gender.
Different levels of resource ownership
- Resource ownership refers to the extent to which households own assets such as wealth, property, or capital that generate income.
- Some individuals benefit from inherited wealth, generating high returns, while others have no inherited access to such resources.
- Resultantly, those without inherited assets must rely solely on wages, which may not always provide sufficient income to cover basic needs or enable wealth accumulation.
- Furthermore, low-wage earners often cannot afford to buy property and must rent instead, which often consumes a significant portion of their income, further limiting their ability to save or invest. Overtime, this cycle of poverty exacerbates economic inequality.
Different levels of human capital
Human capital
Skills, abilities, good health, and knowledge utilized by people to increase their productivity.
- Wealthier individuals can afford better schooling and higher education, providing them with more opportunities to accumulate human capital and secure higher-paying jobs.
- On the other hand, low-income individuals may face barriers such as expensive tuition fees, limited access to quality schools, or early entry into the labor market, preventing the acquisition of high-income-paying skills.
- Since people without high human capital are often restricted to lower-paying jobs, the differences in human capital tends to widen income inequality.
- Furthermore, lower levels of human capital in one generation can perpetuate inequality in the next. This is because parents with lower income and limited education often cannot provide their children with the resources to develop higher levels of human capital.
Human capital also includes levels of health:
- Low-paying jobs are often more physically demanding or health-damaging, which can worsen health outcomes for lower-income individuals.
- This contributes to further inequality between the rich and the poor, as poor health can reduce productivity and limit income opportunities.
Discrimination (gender, race, and others)
- Discrimination occurs when individuals are treated unfairly based on characteristics such as gender, race, or ethnicity.
- This can potentially limit access to jobs, education, and other opportunities, for the people who may be part of certain communities.
Women may be paid less than men for the same work, or minority groups may face barriers to employment due to biased hiring practices.
Unequal status and power
- Individuals or groups at the top of social or political hierarchies often hold significant power: they can shape laws, regulations, and institutions in ways that preserve or enhance their economic advantages, making it harder for low-income households to climb the social ladder.
- Those with higher status and power often have control over critical resources, which allows them to secure higher incomes and wealth while limiting access for others.
- Contrarily, disadvantaged groups may face institutionalised discrimination (unequal voting power, biased judicial systems...), perpetuating economic inequality.
- Furthermore, those in positions of power often pass down their advantages to their descendants. This perpetuates a cycle where power and wealth b concentrated in the hands of a few.
Government tax and benefits policies
- Household on lower incomes, typically receive government benefits, on which they heavily depend on.
- Therefore in case of reduction or removal of such benefits could increase the economic inequality.
- Furthermore, governments' tax systems tend to favour the rich:
- This is because the same percentage of tax represents a higher percentage of the income for essential neccesities the poorer one is.
- Therefore, tax systems impact people on lower incomes more, constraining their incomes, and hence further increasing economic inequality.
In the fictional country of Econland, both low-income workers and wealthy business owners pay a flat income tax rate of 20%.
- Anna, a factory worker earning $10,000 annually, pays $2,000 in taxes, leaving her with $8,000 for essential expenses like food, rent, and healthcare. This represents 25% of her disposable income spent on necessities.
- Liam, a business owner earning $1,000,000 annually, pays $200,000 in taxes, leaving him with $800,000. This allows him to save and invest the majority of his income after covering his living expenses.
Therefore, while the tax rate is the same, it disproportionately affects Anna, as a larger share of her remaining income goes toward basic needs, limiting her ability to save or invest. This system reinforces economic inequality, as Liam's wealth grows while Anna remains constrained.
Globalisation and technological change
- Since the Industrial Revolution, the development of technology has accelerated, where technologies get more productive, functional and efficient at what they do.
- These advantages of technology therefore leads many employers to replace their workers with technology to increase efficiency and cut labour costs.
- Most of the people getting affected by this job cut, are the low-skilled, low-earning workers.
Automation in manufacturing has reduced demand for factory workers (generally low-income workers), while increasing demand for tech-savvy professionals (generally high-income earners).
Market-based supply-side policies
We will learn more about market-based supply-side policies in section 3.7.2.
- Policies like deregulation and privatisation aim to increase efficiency in markets.
- Such policies allow private firms to fire low skilled workers and replace them with technology by deregulating labor protection laws.
- These policies often benefit those with capital and skills, leaving low-skilled and low-income people behind.
Privatizing public services can lead to higher costs, making them less accessible to low-income households.
