Migration – good for recipient and sending countries?

According to the World Bank in year 2000 36% of migrants in 20th richest countries were highly skilled. Do sending and receiving countries benefit or suffer from high-skilled migration? Without immigrants, ageing societies with low natural birthrate would have to cope with economic slowdown. Especially economies in America and Europe with increasing demand for high-skilled workers and in need for people willing to do hard and unpleasant jobs. Not enough young natives have the right skills or motivation, so the rich must hope that outsiders will keep coming. And they will as long as such wealth differentials persist, the draw will continue. It is more complicated issue in sending countries. Poorer countries could benefit from emigration in general till the natural birthrate is higher than emigration rate, then emigration could lead to lower poverty and higher wage level (examples Belize, El Salvador, Guyana, Jamaica). Although remittances and new skills are claimed to be beneficial there is no guarantee emigrants will return. Exporting better brains will harm sending economy in long term. Poor and middle-income countries in North-Africa, Pacific and Caribbean region face shortages of skilled workforce, well qualified workforce will emigrate leaving most critical jobs unfilled at home, so there hardly will be potential for economic catch up.See more Economist.com
