"It was totally unlivable."
"All died fighting in the war. The only people left in Germany were women, children and old men.
"Did they have to bring young men in from America and Canada to help rebuild Germany and all the other European countries destroyed by the war?"
"I still don't know how these countries survived with so few young men left! "
IGNORANCE. Yes, they lost a lot of young men, but far from all of them. It was "only" 23% killed. \There were plenty left to help rebuild, and there were immigrants from other countries, plus the US Army Corps of Engineers, and the British equivalent. It was East Germany that really suffered because the Russians did so little for so long.
