I went thru the UK's Winter of Discontent as a child. Power cut's, food rationing, the whole works. My brother, sister and myself were Shielded from the worst of it by our parents.
My parents grew up during the second world war and it's aftermath. I think that experience made many people natural preppers. Even if they do not think of it in those terms. You could say that the views of the parents are reflected in the child.
