Are you teaching children to make money online?
We are teaching children how money, findability and ownership work. That is not the same thing as pointing a nine-year-old at the internet and telling them to go earn.
Everything through the Builder Years is offline and conceptual: lemonade stands, bracelets, a page drawn on paper, a chart of how many cups sold on a hot day.
The Founder Years books, for twelve and up, do get practical about pricing and selling something real, and they are explicit that an adult is involved in anything that touches actual money or actual strangers.
