So, your son or daughter is elementary age. Too young to work, right? Certainly too young to make millions of dollars, correct? Nope. Jr. could be making bank right now just like Ryan Kaji. Never heard of him? Well, Ryan is the highest-paid star on YouTube, and he didn't even start wiping his own tush until Game of Thrones was four seasons in...

Ryan is only 8 years old, and his Ryan's World YouTube channel raked in $26 million over the past year. He was also ranked #1 last year, with $22 million.

Ryan's channel launched five years ago, and used to consist mainly of him unboxing toys. Now he's posting several videos a week, doing whatever... Including one where he grows his own bacteria, which you can see below. For his efforts, he has almost 23 million subscribers.

The second biggest channel this year was Dude Perfect, those five guys who play sports, perform stunts, and break Guinness World Records. They made $20 million this year.

Coming in third was 5-year-old Anastasia Radzinskaya, who earned $18 million. Ohh to be 5 or 8 years old again...
