Chapter 04

Jobs & What People Make

Primary

Every job makes something the rest of us need or want — food, houses, haircuts, or fixing a broken bike. Let's see how jobs connect to everything you use.

At a glance
Core ideaEvery job makes a good or a service that the rest of us use.
Key termSpecialisation — getting great at one job and buying the rest.
You can…Tell a good (you can hold it) from a service (done for you).
Watch outPay differs with training, risk and how rare the skill is.
Theory

Goods, services and income

Jobs make two kinds of things. A good is something you can hold — bread, a chair, a bicycle. A service is something a person does for you — a teacher teaching, a doctor helping you feel better, a hairdresser cutting your hair. The money a person earns from their job is called income.

Most people don't make everything they need themselves — they get very good at one kind of job, and use their income to buy everything else they need from other people who specialise too. This is called specialisation, and it's why we all get better food, houses and toys than if each of us tried to make everything alone.

Explanation

How one loaf of bread takes many jobs

Think about your breakfast toast. A farmer grows the wheat. A miller grinds it into flour. A baker turns the flour into bread. A shop worker sells you the bread. Four different jobs — and probably many more, like the truck driver who delivered it — all combine so you can have toast this morning. Nobody had to do all of it themselves.

Farmer grows wheat Miller grinds flour Baker bakes bread You eat the bread!
Many jobs, one loaf of bread: each person specialises in one step of the chain.
Practical

Try it: good or service?

Sort each job into Good (makes something you can hold) or Service (does something for you):

JobGood or Service?
Carpenter (builds a table)Good
TeacherService
Farmer (grows apples)Good
DoctorService
FirefighterService
Step 1A table you can touch and keep → it's a good.
Step 2A doctor helping you get better isn't something you can hold → it's a service.
Q&A
Q1Why do people get paid different amounts for different jobs?

Some jobs take many years of training, are riskier, or need a very rare skill, so those jobs often pay more. A later, more grown-up chapter (Chapter 11) explains this properly — for now, just know it's usually about how much training and how rare the skill is.

Q2Can one person have more than one job?

Yes! Many people have a main job and also do small extra jobs — like mowing a neighbour's lawn — to earn a little more income.

Q3What would happen if everyone tried to grow their own food, build their own house, AND make their own clothes?

Everyone would be much worse at all three, and have far less time and far fewer things overall. Specialising — each person getting great at one job — is what lets a whole town have plenty of good food, sturdy houses and warm clothes.

Solved examples

Worked problems, step by step

Follow each solution line by line, then try to reproduce it on paper before moving on.

Example 1A baker, a doctor, and a bus driver -- which one makes a good you can hold?

  1. A good is a thing you can touch.
  2. The doctor and driver give services (help and rides).
  3. The baker makes bread, a thing you can hold.

Example 2Your bike is broken. Whose job helps you?

  1. You need someone who fixes bikes.
  2. A bike mechanic does the repair as a service.
  3. So their job connects to your need.

Work each one out first, then tap to reveal the worked answer.

1What is the difference between a good and a service?
A good is a thing you can touch; a service is a helpful job someone does for you.
2Name the job that grows the food you eat.
A farmer -- farmers grow crops and raise animals for food.
3Is a haircut a good or a service?
A service -- the barber does work for you; you cannot hold a haircut.
4Why do we need many different jobs?
No one can make everything, so each job makes something the rest of us need or want.
5Who makes the houses people live in?
Builders (and other workers like plumbers) make and fit out houses.
