Depression era people kept reusable things in spades and also cared a lot more about social networks (real social networks) more than anyone since. If you had a streak of good luck you banked some of it with your network, because you never knew when the other shoe might drop and you needed to make withdrawals.
This gave me a good chuckle, thank you!
It's actually the same for me, only my parents were the cause not theirs and I honestly hate them for it.
Same anxiety here, even though I'm in my early 40s.
In my case though is not the fault of my parents, but of the general socio-economic conditions back in my adolescence years (the '90s were hell for some of us in Eastern Europe) that saw my family move from middle-class status to almost destitute in just 2-3 years. My dad actually felt (probably still feels) pretty guilty about it all, even though it was not his fault, the socio-economic forces in play were just too great. I just hope I won't pass the same feeling of financial insecurity to my kid(s).
