Okay kiddo, have you ever heard of the word propaganda? It's when people or groups try to influence what we think or do by giving us information that might not be completely true or fair. Capitalist propaganda is when this happens specifically with businesses and people who believe that capitalism (which is when people and companies can make and sell things for money) is the best economic system.
So let's say a big company wants to sell a new toy. They might make an advertisement that shows happy kids playing with the toy and saying how much they love it. That's advertising, which is a way of promoting a product. But if the company also says things like "this is the only toy you'll ever need" or "all the cool kids have it", they're trying to make people think that they need the toy, even if they actually don't.
This kind of messaging can also happen in other ways, like news stories or social media. Sometimes people who support capitalism will say things like "if you work hard enough, you can be rich one day too" or "poor people just need to try harder and they'll be successful." But the truth is, not everyone has the same opportunities or resources, and some people face more challenges than others.
So, capitalist propaganda can be tricky and try to make us believe something that might not be entirely true. It's important to always ask questions and make up our own minds about what we think is right or fair.
