Since I'm currently part of that immigrant pool, I found this article in the Washington Post to be quite compelling. The remarkable article of East to West Migration speaks about a 39 year old man named Janis Neulans from Latvia and his struggle to immigrate to Ireland.
The article brings about the possible exploitations of new workers coming into the country and how welcoming the Irish are for these new immigrants. Why? Because they were in the shoes long ago. Many job rich countries such as Ireland, Britain and Sweden are welcoming immigrants while France Germany and other EU members aren't doing so. I'd say Switzerland is in the pool with France and Germany too. It's quite an eye opening account of one man following his dream.
