The Big Bucket
Governments use something called money printing. It is not literally pressing buttons on a printer to make paper bills. Instead, it means creating new digital numbers in the bank accounts of businesses and banks. When the government needs to spend money on roads or schools, it can simply add those funds.
Why Not Just Keep Printing?
If the government prints too much money while not making more toys for people to buy, prices go up. This is called inflation. It means your ten marbles are now worth less because everyone else has ten marbles that cost more cookies.
The Goldilocks Zone
We want just enough new money to help the economy grow without making prices rise too fast. Central banks are like careful cooks who add salt (money) to a soup (the economy). Too little and it tastes bland; too much and it is salty. They watch closely to keep the balance perfect so everyone can afford their favorite snacks.
