Is Switzerland a hell for Expats?

Found this article in a Swiss newspaper ("Blick am Abend"). "Is Switzerland a hell for Expats?". I was also wondering why Switzerland is always ranking high on the lists of best places to live as an expat, but at the same time I hear so many expats having trouble making friends and feeling at home, even though it is a beautiful and safe country. But that's not always enough. What do you think?
