What is mass immigration?

Mass immigration, as a policy of state, means the ability of people from different countries to be able to enter the territory of another with little or no legal impediments. While the effects of this type of public policy are many as is the debate over its merits or disadvantages, there is much evidence to suggest that it does have dire consequences in debilitating the principle of national sovereignty, suppress wages for low-skilled national workers, financially burden the social benefits/insurance programs and weaken the social fabric by groups hostile to the principle of assimilation.
