Sounds like yours are better prepared than most.
The tip off is who the initially less frugal one chose as a mate.
Children of course learn most by watching what their parents do. Many are now at least 2 generations away from what you describe and significantly less prepared for hard times. You can read it in a number of younger Freepers here.
You are right - they way DH and I did things was very much like our parents and grandparents. My mom was not this way, but my grandmother was frugal and always gardened and canned. I learned so much from her and my MIL. I learned how to handle money from my dad and my husband from his dad.
But I think many have gotten away from that - maybe it has something to do with the breakdown of the family unit. I don’t know.
