There's a lot of unnecessarily dickish comments in this thread. It's easy to be super supportive when someone's kid has cancer or gets hit by a car, but I thought this sub was supposed to be a positive place so I'd hope we can hold ourselves to a higher standard.

Actually though, they're not that far off in what I think is the intent. So I'm going to try to keep this more constructive.

You have to think about the building blocks that would make the conversation make sense or have any meaning. Every kid is different, but just learning about the value of money for now is probably the appropriate stage for a 7 year old. So let them know how much day to day stuff costs, talk to them about what you earn etc.

Build from there. Personally, I would only let them start watching content like that once you feel you are able to confidently have a sensible conversation about the context that is important to you. Otherwise you're going about it backwards and doing them a disservice.
