Here's a very different angle on several old topics, including immigration to Poland and death camps in Poland (but not what you're thinking, at all).
There are ants living in a kind dystopian ant-colony in an old Soviet nuclear bunker in Poland. The population is supplemented by ants falling down a broken ventilation shaft (immigration), and the mortality rate is quite high (death camps). Scientists speculate the ants may be cannibalistic, too.
I think this needs to be turned into a novel, with lots of layers of allegory.
