related, if a little girl with a lemonade stand had tappay or a cashapp, I would be pretty impressed.

We mostly romanticize traditional child business stuff (girl scout cookies, lemonade stands, mowing yards, etc). Learning how to sell your work, to know the value of your labor is important. But almost no one pays with cash. If a kid was serious about trying to make money the way we imagine kids could make money they need to be with the times, not with the whimsy.
