I was curious myself, so here's what a robot told me:

Imagine you have a piggy bank where you keep your allowance. Sometimes, you might want a toy that costs more than what you have saved. So, you ask your parents to lend you some money, promising to pay them back later. This is similar to how adults use credit cards—they buy things now and agree to pay for them later.

Now, let's say many people start borrowing more and more money using their credit cards. This means they owe a lot and have to use a big part of their future allowances to pay back what they borrowed. When so much of their money goes to repaying debts, they have less to spend on other things they enjoy or need.

For the whole country, this can be a problem. If lots of people are busy paying off debts, they might buy fewer goods and services. This reduced spending can slow down the economy, leading to fewer jobs and opportunities for everyone. So, while borrowing can help us get things we want sooner, too much borrowing can make it harder for everyone to enjoy a healthy and happy economy.
