These kids are going to be so mad at how low interest rates are at actual banks that I wonder if this is ultimately going to teach them to borrow rather than save. I guess it’s the same thing, really: they’re learning the time value of money either way.
I've been very transparent with them that the interest rates they get from me are far more generous than out there in the real world. :)
Alternatively we’ll have hyper inflation and they’ll be even madder that all their nominal scrimping and saving was meaningless.
