what was the difference between death camps and labor camps?
The U.S. used them in WWII to concentrate or group and isolate japanese americans. A labor camp is one in which the inmates are forced to engage in some form of slavery, often agriculture or manufacture. a death camp is a camp in which the inmates are put to death.
Labor camp inmates may have been treated a very little better than concentration camp inmates because they were useful. Labor camps were brutal in spite of the fact that the inmates were useful and large numbers died, but they were not designed to kill. Death camps, on the other hand, were designed purely for killing.
