The idea

Economic inequality describes how unevenly income and wealth are spread across a society. In many countries wealth is far more unequal than income, because wealth accumulates over time and across generations, and because returns on assets can grow faster than wages. Social mobility describes how easily people can move up (or down) compared with where they started — for example, whether children from poorer families can reach higher incomes as adults.

Researchers measure both in different ways and find large differences between countries and over time. They also disagree about the causes — education, labour markets, taxes, inheritance, discrimination, technology, geography — and about what, if anything, should be done. The personal and the social meet here: individual choices matter, but so does the starting line, which people do not choose.

Why it matters

Understanding inequality and mobility helps people see their own situation clearly — neither blaming themselves for disadvantages they did not create nor ignoring the choices within their control — and take part in public debates about it.

A real example

The situation

Two students with similar grades apply for the same unpaid internship, which leads to a well-paid career.

What happened

One can take it because her family can support her for six months; the other cannot afford to work unpaid and takes a paid job in an unrelated field. Their careers diverge from that point.

The takeaway

Similar ability met different starting points, and the gap widened from there.

How people actually behave

People tend to explain their own success by effort and others’ difficulties by choices, while underestimating the role of starting points and luck — in both directions.

Common mistakes

• Believing outcomes depend only on individual effort.
• Believing outcomes depend only on circumstance, leaving no room for choice.
• Assuming inequality is the same in every country and era.

Different perspectives

Reasonable people disagree here. None of these is presented as the answer.

Inequality mainly reflects different contributions

Some argue that differences in income and wealth largely reflect differences in effort, skill and risk-taking, and that they create incentives that benefit society as a whole.

Inequality mainly reflects unequal starting points

Others argue that inherited wealth, unequal access to education and connections, and discrimination explain much of it, and that high inequality reduces mobility and fairness.

Questions to think about

• Which advantages or disadvantages did you start with that you did not choose?
• What within your control could improve your own or your family’s mobility?

Try it: Starting points

1. List three advantages and three disadvantages you started life with.
2. Mark which were chosen and which were not.
3. Name one choice within your control that could widen your options.

Words in this lesson

• Inequality — How unevenly income or wealth is spread across a society.
• Social mobility — How easily people can move up or down in income or status compared with where they started.
