Imagine you have a huge box of toys, and you want to organize them in a certain way. Just like that, economists have different ideas on how to arrange the way we make and use money.
Think of schools of economics as different toy boxes with different types of toys. Each box has a different set of rules and ideas about how to use and play with the toys inside.
The classical school of economics is the oldest toy box, and it has been around for a long time. It says that markets are perfect and that people always act rationally. Imagine that everyone wants the same toy, and the toy store sells it at a fair price. No one would buy the toy if it was too expensive, and the store would go out of business if it was too cheap. According to this way of thinking, the economy will ultimately take care of itself with very little government intervention.
The Keynesian school of economics is like a second toy box. It is newer and says that sometimes people do not act rationally, and when this happens, the government needs to get involved. It is kind of like when your little brother or sister throws a tantrum because they cannot have a toy they want. Mom or Dad steps in to calm things down and make things fair. Keynesians say that the government should spend money or lower taxes to boost the economy when times are bad.
Another school of economics is called the Austrian school. Imagine a toy box full of building blocks. According to these economists, markets and people act in complex ways that we can’t fully understand or control. It is like building a giant block tower, and every block affects the stability of the tower. The key is to let people do their own thing and not interfere. The market will naturally correct itself.
Finally, there is the Marxist school of economics. Imagine a toy box full of dolls and action figures. This way of thinking believes that there are two groups of people—the rich (called capitalists) and the poor (called workers). Marxists believe the rich use their power to exploit the poor. Think of the rich kid who gets all the toys and never shares with his friends. Marxists want to get rid of the rich/poor system by having workers run everything together.
In summary, schools of economics are like toy boxes filled with different ideas about how to use money, and each one has its own set of rules and ideas. Like all toys, each school of economics has its strengths and weaknesses, and we need to choose which one to play with based on what we want to achieve.
