This final chapter reviews the general findings of our investigations and provides an overview and assessment of the potential lessons for researchers, the public, and the policy-making community. What are the experiences of immigrants in Germany and Denmark, and how different are they? What have been the consequences of different migration and social policies and of differences in the needs of the respective economies? Are there differences between Germany and Denmark in attracting high-skilled and low-skilled immigrants, and how do immigrants adjust their skills when they enter the respective labor markets? What is the level of attachment of immigrants to the labor market, and how is it affected by social and labor market policies? How do immigrants fare with respect to earnings, employment, unemployment, self-employment, welfare take-up, and crime? And how do they impact on public sector finances? What do migrants do that is to the advantage or disadvantage of the natives? The book has covered this broad range of questions, struggling to provide lucid and coherent answers. This chapter summarizes the core findings and provides some clear-cut conclusions.
