This is just the just world fallacy in a post. If you lived in Germany you would understand that statements like this that you wrote:
> doesn't make you a special snowflake worthy of the German society to turn itself upside down for you and roll the red carpet and make life super easy for you
are utterly, utterly ridiculous. There is absolutely no risk whatsoever of Germany "rolling the red carpet" for immigrants. It's a fairly hostile place to be if you're not German even if you're white. It can also be hostile even if you're German but not white. Among "expat" destinations (so plausible expat destinations, so excluding, e.g. DRC), it regularly tops the rankings as the worst place to live (harder to live in than Japan or China, and no disrespect to those two countries, but they are traditionally considered benchmark definitions of exclusive countries).
> Best learn it if you move there out of respect for the host country and to integrate and become part of society
Let me tell you as someone who lives in Germany right now: the vast majority of 1M Syrian refugees will never, ever, ever integrate into German society. I had no opinion on this before I moved here, now it's obvious. Your idea that integration is purely a one way street is nonsense and only leads to broken societies. Even if you change your name to Winfried and got C2 German, you'll still never be accepted here. Maybe your children will be, but maybe not if they're not white. But the fact is that if countries want immigrants to pay for their boomers' pensions, they need to actually be a generally more welcoming and friendly society. "Fuck you, learn German, and go and live in Chemnitz" don't really pass muster these days. I mean for example this is nonsense:
> make you a special snowflake worthy of the German society to turn itself upside down for you and roll the red carpet
As if Germany is doing everyone a favour by letting people move there. If there was no demographic crisis then immigration would be practically impossible. I am doing Germany a favour by moving here at least as much as they are doing me a favour by letting me.
> there not because you've got some super rare skills nobody there had
I'm an academic in a fairly obscure branch of physics so in this case I can categorically say that I do have those rare skills. Everything you said about the country is wrong. Their advice: "don't move here unless you speak German" is absolutely on point, and what I myself tell people. Living in Germany mostly makes no sense if you're not German or not a refugee.
