Goods, Services, and Money

Everything people buy is either a good or a service. A good is a thing you can touch: bread, bicycles, books. A service is work someone does for you: a haircut, a piano lesson, a bus ride. The economy is the giant web of people making goods, offering services, and trading with each other.

Money makes trading simple. Long ago, people bartered - swapping things directly, like trading eggs for milk. That only works when both people happen to want what the other has. Money solves the problem: everyone agrees it has value, so the farmer sells eggs for money, then uses that money to buy anything, from anyone.

Money also teaches choices. Every dollar spent on one thing is a dollar that cannot be spent on another, so people make budgets - plans for what to spend, save, and share. Saving a little regularly adds up surprisingly fast, and it turns big wishes into reachable goals.
