What is it about Berlin?

So, I’m Irish. And I’ve joined a bunch of ‘Expats in Berlin’ groups on Facebook and beyond, as I’m moving to Berlin in the next few months with my job. Have moved numerous times across Europe, and across the Middle East - but my god, i have never seen so many people posting about how they are just after moving to Berlin with no job, no leads on jobs, no permanent accommodation anywhere near in sight and no income. Like 10’s and 10’s of posts from people being like ‘just moved to Berlin, looking for work. I’m qualified as X, but will happily walk dogs or take on menial jobs’. Some people even asking about how they can claim social welfare, immediately after getting there. What is it about Berlin? I’ve not seen it in any other city at this scale! It seriously makes no sense to me. You’re willingly choosing total instability and then resorting to pleading with people for a source of income once you land there! Confused 😵‍💫
