Dunno, we have had huge WWII impact, dictatorship, civil war, and other such things in my parts, and they didn't impact much the generations involved in everyday life. I know tons of people that survived those events. Speaking to friends and relatives it was just things that happened. So it goes, etc.
Maybe they were more lucky. In case of my grandparents, they were children whose parents were executed by Nazis or sent to Auschwitz to die, or who themselves were sent, as teenagers, to a Stalinist prison.
Yes, both kinds of concentration camps are very extreme experiences.
I'm talking more general war and civil war scenarios (e.g. having your city bombed, being in a war, having family members die in such scenarios, etc -- which have been common in many places in the developing world (and Europe).
But the constant terror of a concentration camp for months or years on end is another thing.
