Who writes the gratest textbooks, who's the leader in science if not the Americans?
Germans.
With that kind of approach I strongly doubt that you'd feel comfortable in the US. Considering that I lived in the most educated city in the US I anyway felt how uneducated they were comparing to... well... Russians (not that I'm hooray-patriot but I can't compare to any other nation).
"Life in Poland remains swimming in pudding - it's possible but every move takes two times more energy".
Nice words... but you never know how many moves you in fact need to feel comfortable, to feel that you live. Yes everybody in the US has a car (unlike to Russia), you can feed a couple Africaes with their thanksgiving leftovers but on the other hand you could find all these not challenging... artificial, unnatural.
Finally there're lots of pros and cons.Your right to choose... :)
