In 1933 the first concentration camps also had massive improvised parts. It took about a year for them to be run fully professional. Conditions also became worse over time, with the start of WW2 being a huge step. That was also the start of the extermination camps, which were meant for genocide. Concentration camps were “just” really horrible prisons, which also had criminal and political prisoners, which were actually partly released.

This is just early concentration camp. Good chance it gets worse.
