Vasily Grossman was a Russian-Jewish journalist and fiction writer. His 1959 epic-novel "Life and Fate" opens with a description of a German concentration camp. He tells of the following features, calling them "Nazi inventions":
- Many would end up in a camp for criticising the Nazi regime in a private conversation or even for telling a political joke;
- POWs would end up in a camp for political prisoners, including Western allies' and Soviet POWs in the same camp;
- Workers would end up in a camp for leaving job or even for poor performance;
- Some prisoners were German emigrants who fled Nazi Germany; "whoever left Germany became a political enemy";
- Along with political prisoners, there were criminal convicts (e. g., professional thieves), who were privileged and used by the administration to control the political prisoners;
The novel was not published in the Soviet Union, moreover, Grossman's apartment was raided and the manuscript was confiscated by KGB (though, a copy made its way to the West), with Mikhail Suslov allegedly commenting that it would not be published in the next 200 or 300 years. And indeed, the above features were in fact characteristic of GULAG, which would be recognised by many readers familiar with writings of Solzhenitsin and others. In view of this, nowadays it is hard to read this as anything but a satire of Stalin's regime.
On the other hand, Grossman was a military journalist who advanced with the Red Army and, in particular, interviewed some Treblinka survivors. He definitely knew something about Nazi camps. He seems to talk about a forced labor camp, not an extermination camp, although the camp does have gas chambers and crematoria, and some inmates are selected to be executed. He also gives some details, like colour tags, characteristic for Nazi camps and uncharacteristic for GULAG.
Question: do any of the above points accurately describe Nazi policy and what happened in Nazi concentration camps? Or, at least, were the Nazi concentration camps commonly portrayed that way?
