Okay kiddo, so you know how when we go to the store to buy things, we have to use money to pay for them? Well, sometimes the things we need to buy cost more money than we have, and that can be a big problem.
In the United Kingdom right now, lots of people are having this problem because the cost of living is very high. Cost of living means how much it costs for things like food, housing, and transportation.
See, when things cost more money, but people don't make more money to pay for them, they might not have enough money left over for other things they need or want. This can make it hard for people to afford important things like groceries, rent, and medicine.
Say you have a toy you really want to buy, but you already spent all your money on food for the week. You might not be able to get the toy, even though you really want it.
This is what is happening to a lot of people in the UK right now. Because the cost of living is so high, they have less money to spend on other things they need or want to buy. This can make it hard to live a happy and healthy life.
Some people are working to try and fix this by making things cost less, or by helping people make more money. It might take time, but hopefully someday things will be more affordable for people in the UK.
