I dare you to teach a 4 or 5 year old to use one!
Do you think they'd fare much better with budgeting physical cash?
You don't have kids, do you?
Addition and subtraction are abstract concepts that are learned around age 5-6. It starts with tangible objects, pictures, ect.
Cash is a tangible object that helps teach the concept.
I certainly didn’t. I remember getting cash as a young child, thinking with $20 I was “rich”, and rapidly blowing it on Sim City.
I only understood the value of money once I both had a bank account and a job that funded it.
Sim City isn't a bad way to spend $20 in fairness
