Sweden, dont have any statistics but i know the unemployment is there.
Well, if it's higher than 10% thats a bit alarming. In my country unemployment rate is like in Spain, 25%...
This is how I look on that issue:
In developed western countries with unemployment rate of 4-6%, economy is very healthy, offering a lot of opportunities. It's not that hard to find a place under the sun for yourself in that kind of environment. Because of that, country is able to spend money on social programs for its own citizens who are unable to work. But many abuse those programs. Because of that and current situation in the world many countries decided to give a chance to foreign people who lived in countries that are in war. To give them chance for a better life.
Now there are same social programs for both residents and immigrants. At first they are the same, living at country's expense. But those immigrants have to live like that, because they don't speak language and are unable to work. After certain period they are supposed to somewhat assimilate and start working. In theory, those people can prove to be much more useful to country than those lazy residents who want to live from money they get from state.
Problem is that many immigrants started doing the same as lazy residents. Now, some of them are no different except that resident think they are better because they are born in that country. No one likes foreigners, because they are aliens. People are generally afraid of what they don't understand.
That's definitely not one sided issue, although many residents of those developed countries believe it is. Globalization comes with a price.
