I love this! I wish I could get my niece, who is enamored with socialism, to read it. She probably wouldn't understand it though. She just doesn't "get" capitalism, her indoctrination is complete.
I was stationed in West Germany for my US Army service, and lived with my wife and small child on the civilian German economy. I spoke fairly good German, meaning we got further into the local cultural experience, etc.
Once home I resumed my business degree, and entered graduate school. I wrote a economics class thesis, comparing the post WWII economies of West and East Germany.
The stark difference in results, both in terms of economic prosperity, but also political and personal freedoms is quite well documented. When the wall came don, people wanted to go from east to west, not the reverse.
A similar comparison is available in the two Koreas.
Anyway if your daughter were directed to study such empirical evidence, she might discover it on her own. You know young people object to being "told" things, but are capable of discovering it for themselves.
On the personal-political freedom side of things, an excellent film was made titled "The Lives of Others." It is English subtitled, but in German. Won Oscar for best foreign film.
