Following further consideration we will also include multicultural policies as an alternative type of social boundary, GDP, and symbolic boundaries in the form of aggregate attitudes towards immigrants in the analyses. The first multilevel results based on European Social Survey data indicate that the disadvantage with regard to life satisfaction is highest for TCNs. While anti-immigrant attitudes and political multiculturalism do not play a role, we identify an impact of integration policies and of GDP. Integration policies do not matter for the life satisfaction of natives, indicating that these mechanisms are indeed present only for immigrants. In contrast, GDP plays a role for the life satisfaction for immigrants and natives alike. Finally, TCNs profit most strongly from a lowering of social boundaries in the form of inclusive integration policies: in countries that provide a large set of rights to immigrants, the well-being disadvantage of non-EU-citizens is lowest.
