Okay kiddo, so when we talk about the mirror of production, we're talking about how the things we make and the way we make them reflect back on us as people. It's like when you look in the mirror and the mirror shows you what you look like. The mirror of production is kind of like that, but instead of showing us what we look like on the outside, it shows us what we're like on the inside.
So let's say you draw a picture. The picture is something you made, but it also tells us something about you - what you like, what you're good at, what you're interested in. And if you keep drawing pictures, we can learn more and more about you. The same thing happens when we make things on a bigger scale, like when we build houses or cars or factories. Those things also tell us something about who we are and what we think is important.
Now, the mirror of production also shows us something else: how we treat each other and the world around us. When we build things, we have to use resources like wood, metal, and oil. And sometimes we use up those resources faster than we can replace them, which can be a problem. We also have to pay people to do the work of building things, and sometimes those people don't get paid enough or don't have safe working conditions. This can be a problem too.
So the mirror of production is kind of like a big reflection of all the things we make and how we make them. It shows us who we are and what we care about, but it also shows us the things we need to work on to be better people and take better care of the world around us.
