Riddle me this

Why did the concentration camps have swimming pools and maternity wards?

Why did Hitler send young aryan boys to freeze to death in Stalingrad while Jews got to stay in all expenses paid luxury resorts?

Considering what is commonly called ‘the Holocaust’ was actually just sending the Jews to work who had the luxuries of free dental care, sports teams, swimming pools, their own currency, and even brothel, of which approximately 271,000 truly, tragically died due to disease and starvation because the Allies bombed the supply lines, how bad does it rank with other tragic events in Jewish history willed by God such as the enslavement in Egypt, the Assyrian and Babylonian exiles, and the destruction of the Second Temple by the Romans?
