It's not that great.
I have also lived in America for a year of my life (in Michigan, to be exact).
The wide distances between cities are both a bless and a pain. Germany feels cramped, but you get from one cozy town to another within a few minutes.
Another thing is that while being upper middle class in Germany feels really good, in the states it feels like there are always some super rich people in your city who will do anything to let you know that you're a little, unimportant piece of insectshit.
Also, despite the fact that germans like to portrait americans as ignorant, in the eyes of other european countries we aren't too different.
Make fun of americans who can't tell all their states on a 'murica map?
"JA! AMIS DUMM! XD"
Being able to tell the names of the balkan states on a Europe map?
"NEIN! Das ist something different! >>;("
Bantering about the poverty of other countries while being there as a tourist, KNOWING that many locals will have german language knowledge, also sadly is a common germ behaviour.
A polish woman who learned german at school once told me that one day when she was working as a waitress, a group of young german men who were likely born into rich families made fun of the cheap cars and ugly blockbuildings in her city.
She then spat into their food before serving it.
I like to say that Germany is too big for Europe, but too small for the world.
Our internet is shit.
If I could choose where to be born, I'd choose Germany over America. I've got my own, amazing language, no guns and all in all a peaceful life without any storms, earthquakes or other various nature catastrophies.
No Schoolshootings or random Niggermoments on the streets.
But I wouldn't mind to be American either, as it also comes with its advantages.
Anyway Bernd, you are not missing out. Don't forget that life is about making the best out of the cards you were dealt ;)
