There was/is a long-held fear in Nordic countries that increased international migration would bring people merely/primarily interested in becoming parasites on the body of society. Never intending to integrate or become productive members of society, but to settle for a life on social support.And it probably happens, occasionally.However, the overwhelming majority of migrants/refugees try very hard to become productive members of society, to carry their own weight.In all the welfare magnet theory has NOT proven correct.
