Inadequate cultural integration of immigrants

Inadequate social integration of foreigners
Cultural integration of immigrants is inhibited by non-acceptance of such immigrants by the original community. Finding themselves in an unequal position and their opportunities limited by discrimination and the law, immigrants may cling to their separatism and original 'nationality' as their sole means of strength and unity. However, the maintenance of a separate cultural identity by immigrants causes friction or conflict with the national majority, aggravating discrimination, segregation, and the refusal by the latter to accept any vestiges of the new culture.
Every decade newer immigrants are thought difficult to assimilate in contrast to earlier immigrants. But in each decade the immigrants have adjusted quickly both economically and culturally. Within a decade or two, immigrants tend to earn more than nationals with similar educational characteristics.
