Well, it's something that was "thought" by the older generation to the younger generations. My grandparents grew up post WWI in the Weimar Republic and then lived through WWII, had to repeatedly flee, losing most of their possession because of it. Other families had the same experience, or lost their stuff due to bombings etc. That heavily informed their decision till the day they died, and of course also to some extent influenced/influences my parents' behavior, which in turn influences my and my siblings' behavior to this day. I'm not saying it's rational, but it's very human still.
