What kind of hurdles did Concentration Camps and the treatment of Jews have?

By hurdles do you mean problems? What problems did the camps have? uh many.they should never have been built.or thought of.But humanity will continue to think these things,and some like hitler have the power to do it again.I really hope that doesnt happen again.but genocides are still happening everywhere,and millions of people are dying.|||Please rephase. I don't understand the question, but I have visited Auschwitz..so perhaps I can be some help.
