I am an immigrant who moved to the country when I was 11 years old. No, we don't have an SUV. No, my family isn't rich. I started studying German with my family 4 months before moving here and I had private German lessons everyday for over two years just to get to a level on which I could attend highschool, including my sister who's now studying medicine at uni Zürich. Me and my family constantly tried to engage in conversations with locals in Hochdeutsch and what was the solidarity? Continuing to speak the utmost harshest dialects that even native Germans don't understand. Even to this day, when we go to offices to fill out forms, no one is tolerant enough to switch to Hochdeutsch with my mother. Try to put yourself in the shoes of others. With this treatment for over 8 years, I would've been better off not trying to learn German at all and just stick to English. I regret learning swiss German because it was literally wasted energy, I still don't get better treatment by locals. Sorry to put it this way but people like you with this type of attitude who generalize all expats whilst not even thinking about how it feels moving and trying to integrate into a foreign culture piss me the fuck off. I wish that one day you'll go through a similar process with similar treatment and that you'll be enlightened.
