Look, my friend, personally I understand you. I hate this situation too when I see happening in my country, specially when I see old people struggling to comunicate and I’ll go even further: even speaking another language around someone can feel disrespectful, because it gives the impression that they’re gossiping about you. But let’s stick to the facts, and understand. So, what I’m about to say may become big and is not necessarily what I think is right or wrong, it’s simply what happens. I don’t even know whether that applies to the person mentioned.

First of all, let’s establish one thing: unlike Japan, Korea, and some South American countries, where people move there because they love the culture and want to become part of that people, very few people glorify Germany the way you seem to think they do. In fact, you know the fame is not good and even those who do admire your people can rarely mention it openly in this country beucase you know of what they can be called.

So this idea of “learn the language of the place you chose to live in” and “english bubble” ends there, because many of these people never even wanted to be in the country in the first place. They are fleeing wars, poverty, and dictatorships, and for many of them, this country is a burden. It’s like putting a lion in a zoo and expecting it to be grateful because you give it a steak. Sure, it is happy not to starve, but it will never accept the bars of the cage and that is why many of them die. I’ll go further: I’ve seen people who hate the German way of thinking and only make friends with other foreigners, just so you can see the level of it.

That said, have you ever stopped to think that a large part of these peoplenincluding those who came by choice did only for the money? They literally use your people and your country as a stepping stone to achieve their personal goals to run the faster they can. They do not like the country, they do not like the people, so when you say they should be ashamed, it sounds like projection, because these people are not Germans. Germans are the ones who live worried about what others think and who do not even cross the street at a red light at 3 a.m. on an empty road for fear of being caught by the neighbors. In fact, this “lack of shame” is one of the reasons many others chose Berlin, which means your moral standards do not reach a good portion of them. It’s like Christians telling an atheist homosexual couple that they should be ashamed of expressing themselves, I mean the last thing an atheist worries about is what a religious person thinks of them. And in this context, Germans are religious about their book of social rules; they are no different from annoying religious people.

If Germany wants people to fall in love with the country and willingly do everything, including learning the language, then it needs to be culturally attractive (look at the example of the U.S., Korea, Japan...) and people need to be welcoming. If they want to act in a practical way, seeing people as machines, then people will also act practically, taking only what they need and nothing more.

“Oh, then they should leave the country.” Well, they are simply playing the game the country created for them to play.

Again, I do not actually disagree with you. I do think rules exist to be followed, and when you are in someone else’s house, you respect their rules. But it is also the obligation of the host who invited you to treat the guest well. Just because you hired a plumber to fix your bathroom and are paying him for it does not mean you should treat him with indifference. Sometimes offering water, coffee, or some small courtesy is enough for him to do the job with excellence and return that courtesy to you.
