EC23: The Distribution of Income
Income and wealth inequality: causes, consequences, and government redistribution through taxation and spending. The balance of payments.
The Distribution of Income
Income and wealth inequality: causes, consequences, and government redistribution through taxation and spending. The balance of payments.
Key Fact: Income inequality: the top 20% earn over 5 times more than the bottom 20%. Causes: education/skills gaps, wage differentials, inheritance, and unemployment.
Key Fact: Wealth inequality is even greater than income inequality — wealth (assets, property) is more concentrated than income (earnings).
Key Fact: Consequences: poorer health and education outcomes for low-income groups, social tension, reduced social mobility, and lower aggregate demand.
Key Fact: Government redistribution: progressive taxation (higher earners pay more), welfare benefits (universal credit, pensions), and public services (free NHS, education).
Key Fact: The balance of payments records the UK's international transactions. A current account deficit means imports exceed exports; a surplus means the opposite.

❓ Practice Questions
Q1: Explain two causes of income inequality in the UK.
Q2: Describe how government can redistribute income through taxation and spending.
Q3: Evaluate whether reducing income inequality should be a government priority.
✅ Answers
- Two causes: (1) Education and skills gaps — workers with higher qualifications earn significantly more. (2) Wage differentials — globalisation and technology have increased demand for high-skilled workers while reducing demand for low-skilled workers.
- Progressive income tax (higher earners pay 40% or 45% vs 20% basic rate) redistributes from rich to poor. Welfare benefits (Universal Credit, child benefit, state pension) provide income to those on low incomes. Free public services benefit the poor most.
- Argue for: inequality reduces social mobility, harms health and education, creates social tension. Argue against: some inequality provides incentives (to work harder, gain skills). Conclusion: reducing extreme inequality should be a priority, but some inequality is acceptable as an incentive — the key is ensuring opportunity and a minimum standard of living.
🎯 Exam Tips
- Always distinguish INCOME (earnings per period) from WEALTH (total assets). Wealth inequality is always greater.
- Redistribution uses BOTH taxation (taking from rich) AND spending (giving to poor).
- Balance of payments deficit = imports exceed exports of goods and services.

⚠️ Common Errors
Watch Out!
Students often make mistakes here. Wrong: Progressive taxation always reduces inequality because it takes more from the rich. Correct: Progressive taxation reduces inequality through taxation but may not reduce it overall if: government spending is regressive, tax avoidance means the rich don't pay their full share, or indirect taxes (VAT) are regressive. The net effect depends on the TOTAL tax and spending system.
✍️ Model Answer
Full-Mark Response
Evaluate whether the UK's balance of payments deficit is a serious economic problem.
A grade 9 response will: explain the deficit (UK imports more goods than it exports); analyse causes (deindustrialisation, strong pound, low productivity); evaluate seriousness (deficit means living beyond means, financed by borrowing; but UK has services surplus and attracts investment); conclude: persistent deficit is concerning long-term but manageable short-term if the UK can continue attracting investment.

Detailed Notes: The Distribution of Income
How Income Is Distributed in the UK
Income distribution refers to how total income is shared among the population. The UK has significant income inequality: the top 10% of earners receive around 35% of total income, whilst the bottom 10% receive less than 2%. The Gini coefficient, which measures inequality on a scale from 0 (perfect equality) to 1 (perfect inequality), was approximately 0.35 for the UK in 2023, higher than most European countries but lower than the United States. UK inequality increased sharply in the 1980s under Thatcher (the Gini rose from 0.25 to 0.35) and has remained high since. Regional inequality is also stark: average household income in London is over 50,000 pounds, compared to under 30,000 in parts of Wales and Northern England.
Wealth inequality is even more extreme than income inequality. The wealthiest 10% of UK households hold around 45% of all wealth, whilst the least wealthy half hold less than 10%. Wealth includes property, pensions, financial assets and physical assets. Housing wealth is particularly unequally distributed because homeownership rates vary dramatically by region and generation: over 75% of UK pensioners own their home outright, compared to less than 40% of 25-34 year olds. This generational wealth gap has become a major political issue in the UK.
Real-World Example
The UK's gender pay gap illustrates one dimension of income inequality. In 2023, the median gender pay gap for full-time employees was 7.7%. This means that for every 1 pound earned by a man, a woman earned 92.3 pence. The gap is wider for older women and those in senior roles. The government requires large employers to publish their gender pay gap data, revealing that in some sectors (like finance), the gap exceeds 20%. Causes include occupational segregation (women are concentrated in lower-paid sectors), the motherhood penalty (career breaks reduce earnings), and discrimination.
Causes of Income Inequality
Income inequality has multiple causes. Differences in education and skills create wage inequality: UK graduates earn on average 10,000 pounds per year more than non-graduates. Globalisation and technological change have increased demand for highly skilled workers whilst reducing demand for low-skilled workers, widening the gap. The decline of union membership (from 13 million in 1979 to 6.5 million today) has reduced workers' bargaining power at the lower end of the income distribution. Tax policy changes in the 1980s (cutting the top rate of income tax from 83% to 40%) benefited high earners disproportionately. The growth of the financial sector in London has created extremely high salaries for a small group of workers.
Structural factors also play a role. The UK's housing market creates wealth inequality between homeowners and renters: house prices have risen over 500% since 1990, benefiting those who owned property. Regional economic disparities mean that people in London and the South East have access to higher-paying jobs. Disability, ethnicity and gender all affect earnings: the UK's ethnicity pay gap means workers from some ethnic minority backgrounds earn significantly less than white British workers on average. Intergenerational inequality is growing: today's young people face higher house prices, higher education costs, and lower real wage growth than their parents' generation.
Real-World Example
CEO pay in the UK illustrates the extreme end of income inequality. The High Pay Centre reported that the median FTSE 100 CEO earned 3.4 million pounds in 2022, approximately 118 times the median UK worker's salary of around 29,000 pounds. In 2000, the ratio was around 47 times. This dramatic increase in executive pay relative to average workers has been driven by stock-based compensation, globalisation of executive labour markets, and weak board-level oversight of executive pay.
Government Policies to Redistribute Income
The UK government uses several tools to redistribute income. Progressive taxation means higher earners pay a larger share of their income in tax: the 45% additional rate applies to income above 125,140 pounds, whilst the personal allowance means the first 12,570 pounds is tax-free. National Insurance is also progressive up to the upper earnings limit. However, the overall UK tax system is only moderately progressive because indirect taxes like VAT are regressive. The Institute for Fiscal Studies estimates that the bottom tenth of households pay around 47% of their income in all taxes, compared to 34% for the top tenth.
Benefits and transfers are the main tools for reducing inequality. Universal Credit (replacing six legacy benefits) provides a safety net for low-income and unemployed households. The state pension is the largest single benefit payment, protecting older people from poverty. Child Benefit supports families. Housing Benefit helps low-income households afford rent. Taken together, the UK tax and benefit system reduces the Gini coefficient from around 0.50 (before taxes and benefits) to around 0.35 (after), showing that redistribution significantly reduces inequality. However, the system is not perfect: benefit cuts under austerity, the two-child limit on Universal Credit, and the benefits cap have all reduced the redistributive effect in recent years.
Real-World Example
The UK's Universal Credit system has been controversial since its introduction. Designed to simplify the benefits system and make work pay, it replaced six existing benefits with a single monthly payment. However, the five-week wait for the first payment pushed many households into debt and food bank use. The Trussell Trust reported that food bank use in areas where Universal Credit had been rolled out was over 50% higher than in areas still using the old system. This shows how even well-intentioned redistribution policies can have unintended consequences.
Comparison: Tools for Redistributing Income
| Tool | How It Works | Advantage | Disadvantage | UK Example |
|---|---|---|---|---|
| Progressive income tax | Higher earners pay higher rates | Targets those with most ability to pay | May discourage work and investment | 45% rate above 125,140 pounds |
| Universal Credit | Means-tested benefit for low-income households | Provides targeted support to those in need | Five-week wait, complexity, sanctions | Over 6 million claimants in 2023 |
| National Living Wage | Legal minimum for workers aged 21+ | Reduces in-work poverty directly | May increase costs for small employers | 11.44 pounds per hour from April 2024 |
| Free public services | NHS, state education available to all | Universal access ensures no one excluded | Expensive; benefits higher earners too | NHS free at point of use |
Additional Practice Questions
Q1: Explain how the UK tax and benefit system reduces income inequality, using the concept of the Gini coefficient.
Q2: Evaluate whether the UK government should do more to reduce income inequality.
Additional Model Answers
- Before taxes and benefits, the UK Gini coefficient for original income (wages, investment income, etc.) is approximately 0.50, indicating significant inequality. The tax system reduces this slightly by taking a larger proportion of income from higher earners through progressive income tax and National Insurance. But the biggest reduction comes from the benefit system: means-tested benefits like Universal Credit, Housing Benefit and Pension Credit provide income to the poorest households, whilst universal benefits like the state pension and Child Benefit support specific groups. After all taxes and benefits are accounted for, the Gini coefficient falls to approximately 0.35. This means the tax and benefit system reduces inequality by roughly 15 percentage points on the Gini scale. Cash benefits are the most redistributive element because they go disproportionately to lower-income households. Direct taxes (income tax, NICs) are the most progressive element of taxation, whilst indirect taxes like VAT are regressive and partially offset the redistribution achieved by direct taxes.
- Arguments for doing more include: the UK has among the highest inequality in Western Europe, with significant social consequences including worse health outcomes, lower social mobility, and higher crime rates in more unequal societies (as research by Wilkinson and Pickett has shown). Child poverty affects over 4 million UK children, with long-term consequences for their education, health and future earnings. Inequality of opportunity means talented people from poorer backgrounds cannot fulfil their potential, reducing the economy's productive capacity. However, arguments against more redistribution include: high taxes may discourage work, entrepreneurship and investment, reducing economic growth and ultimately making everyone poorer; some inequality is fair because it reflects differences in effort, skill and risk-taking; and the UK already spends over 300 billion pounds on social protection, a significant fiscal burden. There is also a trade-off between equality and efficiency: excessive redistribution may reduce the incentives that drive economic growth. On balance, the UK should aim to reduce the worst extremes of inequality (particularly child poverty and in-work poverty) through targeted measures like a higher National Living Wage, better access to affordable childcare, and progressive tax reforms, whilst avoiding excessive taxation that could damage economic incentives and growth.
