I don't think there's anything interesting about that, why should they know how to balance a checkbook? I am 34 and I know how, because it was commonplace when I was 16-20 years old because there was no online banking or online bill payments, and checks were a normal form of payment. But by the time I was 20-22 that stuff melted away and about the only place you can even use a check anymore is the DMV or the grocery store (if you so choose, which nobody does). The DMV is the only place I use a check these days just because they charge a lame fee for using a card, but you CAN finally use a card at the DMV also. I certainly wouldn't expect a 22 year old in 2018 to be able to balance a checkbook, it's an utterly useless skill at this point.
