Camps are only a small part of the problem. What do you do next ? The question is how do you handle such big influx of people without collapsing and without treating them like cattle, the answer to that is: you can't and you'll never be able to.
What people don't seem to understand is that a homeless dude in Germany has it better than 80% of the world outside of the US/EU. Is it unfair ? yeah sure, can you solve it though massive migration ? No, you couldn't fit 10% of the third world in the US/EU without making it collapse.
Seeing other comments downvotes it seems like this topic isn't even open for discussion anymore. Why does everyone have to go emotional and compare everything to Nazi Germany ? When you want to "march" on something you first have to understand why it's there and how it came to be. The cold truth is that this topic is extremely complex and all the solutions that are less than XX pages long can be completely ignored on the spot.

Having a cultural narrative of guilt for actions of others imposed upon the descendants of people who actually fought them is insane and it will end up with a reaction of its own. There's only so long you can call people horrible names before they lose their power, and you end up with young people like youtuber Soph who are _so over_ caring about being labelled in this fashion. When the words lose their power, and when continual attempts to silence dissent fail, what's next?
