Bevelander observes that economic and structural changes in the European economy have led to a gradual increase in the low-skilled service sector, as well as an increased demand for educated workers in the production of high-tech content. The increase in the number of humanitarian migrants being received by European states, as well as the subsequent family reunion migration, has further weakened the economic integration of migrants in Europe. In addition to this, these migrants have to overcome a number of thresholds to be successful in the labor market. Policies addressing this problem have primarily focused on an individual migrant's shortcomings but have not addressed the structural barriers individual migrants face, which hamper their economic integration. Continuation of this state of affairs will both increase marginalization and segregation of immigrants and contribute to growing anti-immigrant sentiment, thus undermining the legitimacy of migration and welfare states.
