My mate, learn German and be happy they don't ask for B2 or C1. If I move to China and want the nationality, it's absolutely normal that one expects me to speak Chinese.
As an Ausländer (who reached C1), I am surprised that you are not talking about the other actual and terrible problems the german society is facing: an aging population relying on immigrants to fill in the gaps, taxes everywhere without the advantages of a strong social system, a very expensive health system but with doctors almost prescribing you tea to fight cancer, crippling solitude inherent to the german culture which even spreads to immigrants -more than half of Berlin lives alone-, a housing market held by boomers and huge corporations (literally no houses below 200k€ in the whole country) which leaves you to rent your whole life to shelter your family, a pro-russia, pro-Afd east Germany vastly undevelopped and uneducated compared to the west. And also food, love, conversations. Germany often feels like the bad sides of northern Europe have been mixed with the bad sides of southern Europe.
And then the glass ceiling does not come at B1, but when you start to notice the difference in behaviour the Germans make between C1 and C2. If you want to pursue your whole career in this country, given how strong the german identity is, you will have to know every single subtlties of the language and culture if you are willing to compete for the next step in your career, for instance a management position.
Really, this country has been in a bad shape for at least five years now. Germany lived until now on its bounce after the reunification, the money poured by the Americans after the war and cheap russian gas. Now it feels like the bill other european countries always had to pay in the last decades has been finally handed to Germany.
Yet again another journalist who read too much science fiction and should stop overestimate a bunch of rocks conveying electrical pulses. Or is this simply to get more clicks?
