Can Immigration Policy Help to Stabilize Social Security Systems?

One of the distinguishing features of most European countries is the importance of social security. Security in all its aspects seems to be relatively more appreciated than in other parts of the world. This is at least the conclusion one has to come to when looking at the size of social security budgets in Europe. It is typical that social security is not part of a federal or local budget but is organized in special funds that can vary their contribution rates without the decision of a parliament.
