Look around your town: a farmer grows food, a builder puts up houses, a doctor keeps people well, a driver delivers parcels. Nobody does all of these jobs alone. Why not?
Doing it all yourself, long ago
A very long time ago, some families tried to do everything themselves: growing their own food, building their own home, making their own clothes, even trying to treat their own illnesses. It took an enormous amount of time, and nobody could become truly excellent at any one thing.
Specialisation: everyone does what they are best at
Today, instead, each worker usually focuses on one kind of job and becomes very good at it. This is called specialisation. A farmer focuses on growing food. A builder focuses on building. A doctor focuses on healing. Because each person specialises, they get much better and faster at their one job than if they tried to do everything.
Match each worker to what they specialise in:
- Farmer
- Growing food
- Builder
- Putting up houses and buildings
- Doctor
- Keeping people healthy
- Delivery driver
- Moving goods from place to place
Work is exchanged for wages
Because the farmer only grows food, and the builder only builds, they cannot simply keep everything they make for themselves — they need clothes, medicine and many other things too. So each worker exchanges their work for wages (money paid for doing a job). They can then use those wages to buy the things that other specialists have made.
Why so many different jobs?
Because everybody needs so many different things — food, homes, health, transport, teaching and much more — a whole economy needs a huge mix of jobs, each contributing one piece. Together, all these specialists produce far more than any one person or family ever could alone.
