The capitalist system developed in Europe because people wanted to make more money and have more stuff. In the olden days, people would trade things like cows for chickens or bread for cheese. But then, people started using money to trade instead of just stuff. This made it easier for people to buy and sell things. Eventually, some people got really good at making money and they became really rich. This made other people want to do the same thing, so they started their own businesses and made even more money. And that's how the capitalist system started in Europe.
