One of my neighbors when I grew up was part of Hitler Youth, and had moved to the US after the war. (for time context, I'm in my mid 30s, and he died a decade ago at IIRC 95 or 96, and I asked him about it maybe 20 years ago.)
I asked him if he and his fellow youths knew of anything. He said at first, no, but pretty quickly when all the jewish-owned businesses vanished almost overnight, everyone knew something was up. Did they know about the camps? Debatable. But even the kids knew that they jewish population was kicked out of society.
