ChainWhat it assumes · how to break it
Start
Education is a merit good with external benefits, but if it is sold at a market price, families must pay for it themselves.
1
As a result, demand for education depends on the ability to pay as well as on its benefits.
effective demand · ability to pay
effective demand · ability to pay
Assumes: Education is priced in a market.
But: In the UK state schooling is free up to 18, so price applies mainly to private schools and some adult courses.

This means children from low-income households consume less education than children from high-income households of the same ability.

Assumes: Low-income households cannot borrow to pay.
Assumes: Low-income households cannot borrow to pay.
But: Student loans let students borrow against their future earnings, so ability to pay today matters less for higher education.

Consequently, they build less human capital and earn lower wages as adults.

Assumes: Education is the main route to higher pay.
But: Apprenticeships and on-the-job training can also raise skills and wages.

Therefore, income inequality persists across generations, which is unfair because access to education depends on parents' income.

Assumes: Fairness means equal opportunity.
But: Some argue unequal outcomes are fair if they reflect effort and choice, so views on equity differ.
End
The outcome is inequitable: low-income households miss out on education, so inequality of opportunity and income persists across generations.
Evaluation chain
- E1However, whether low-income students miss out depends on whether they can borrow to pay.
- E2Because UK student loans are repaid only once the graduate earns above a set threshold, the cost does not have to be paid upfront.
- E3As a result, the price of a degree is much less of a barrier to entry for students from low-income households.
- E4So the unfair outcome is smaller for higher education than the chain suggests, though debt aversion may still deter some low-income students.

No standard diagram. Evidence on how participation in higher education varies with household income makes strong support.

Free state provision → access no longer depends on income, which narrows inequality of opportunity, though quality may still vary by area.
