World War 2... work camp conditions?

Work camps during the second war were horrible, usually established to punish Jews or in Russia the anti-Communists factions, or pro-Orthodox Chruch factions (in the Ukraine the camps could have been either one of these), while at the same time demanding that they work to support the very governmental institutions that are attempting to eradicate them. Simply put, the work camp was a place to go, to give ones labor in support of a government that is trying to kill you. Kind of ironic. From the government's point of view, the work camps were places where workers were used and exploited, given as little as possible in terms of food, clothing and medical care, so that they could continue working but would cost the state next to nothing. Men and women were segregated, there was no such thing as the elderly or children, all there were were laborers who could do the work, or there were the dead. Food usually consisted of a thin porridge or gruel, with little taste and little nutritional value, this could be made from potatoes or wheat or grain, perhaps with tiny amounts of fat thrown in, or even cabbage or an onion or other tubular vegetable. Clothing was sparse and ill-fitting. Sleeping conditions cramped and often cold, or hot.
