The benefits of labor migration are usually questioned in the US. Why does skilled workforce enter the foreign market? Do not they have their own country to contribute to? Many Americans think so taking into account rates of unemployment and a fierce competition in the workplace. Nevertheless, migrants are known to benefit the labor market, participate in social life, and stimulate economic growth. In many European countries, migrants enjoy extensive rights. Canada, Australia, and New Zealand accept labor migrants as a valuable social layer.
Immigrants are important because they usually take the most dynamic occupations. Whether they are high- or low-skilled, migrants fill the gaps in occupations that look unappealing to domestic employees or lack career prospects. Healthcare, education, STEM-professions, production, maintenance, and repair frequently need more than the domestic labor market can offer and take advantage from migrants in some countries.
Some researchers suggest that immigrants make no dramatic impact on GDP of countries after all. Europe, as well as the US, Canada, and Australia add extra 0.5 percent to their annual GDP due to labor immigrants. Nevertheless, a part of immigrants arrives with valuable skills that sufficiently impact domestic industries of the host country. Migrants are widely known to boost innovation and research, thus push forwards technological development.
Even if benefits brought by immigrants do not allow economies to thrive right away, we shall not forget about the gaps filled by high- and low-skilled foreign workforce. Deterioration of industries would drag down GDP anyway, therefore, many countries depend on seasonal migrants at least.
