Ratifying the U.N. Convention would increase unemployment rates in receiving countries at a time when they are already painfully high  Increasing protections of migrant rights has the general effect of increasing migration. Article 8 of the U.N. Convention grants all workers the right to leave their state of origin. This implies an obligation of other states to receive them, and so it would protect increased migration. Further, the right to family reunification for documented migrants, found in Article 50, would also increase migration.  This increase in migration would be problematic in many countries. It could worsen overpopulation problems, increase tensions between ethnic and/or religious groups, and raise unemployment rates. The economies of many receiving countries are barely managing to fight unemployment in the status quo. If migrants receive further protection, they will take more jobs, making it harder for citizens to find employment. Everybody should have the opportunity to work in his home country, but the economic protection of migrants overcrowds receiving countries, driving up unemployment. In America, for example, between 40 and 50 percent of wage-loss among low-skilled workers is caused by immigration, and around 1,880,000 American workers lose their jobs every year because of immigration. [1] In addition to unemployment problems, overcrowding can have a variety of negative consequences affecting air pollution, traffic, sanitation, and quality of life. So, why are migrants deserving of "protection"? It should be the other way around: the national workers of a state deserve protection from migrant workers and the jobs they are taking.
