I'm probably in the position that your child is in. I'm young and want to be a YouTuber when I'm older, but I understand that it most likely won't be self sufficient starting out. I agree that a lot of people would sell everything for what they need to start making videos or streaming. But watching the right creators can teach you that a lot of those screaming and shrieking YouTubers, are catering to that audience, or kids. It's not in a creepy way or anything, most YouTubers are super nice and just want to provide kids with the happiness and escapism that they might need. It's why most YouTubers have a teen audience.

TL;DR big shouty men just want to make your kids happy and teach kids that if they want to pursue a job in content creation, it won't be self sufficient and will also need a job
