I propose an assessment of the main aspects of migration in Europe since 1990. The current situation is very unfavorable for a regular and stable insertion of immigrants. Millions of immigrants are integrated in Europe, but their moral and material costs are always too high. Many of them are forced to flee elsewhere or to return to their own countries. The great economic development of the past twenty-five years has been the product of millions of temporary or completely black workers (nationals and immigrants). The reproduction of irregular migration is useful for the shadow economies. The lack of any legal security has brought to a sort of neo-slavery, always combined with racial criminalization
