122. We live in an age of global migration, with more migrants moving in more ways to more countries than ever before. As in the past, this migration is mostly beneficial for the migrants that move, the countries that welcome them, and the countries they leave. The challenge is to manage the migration that is occurring in a way that maximizes benefits for all parties involved.
123. Origin countries have begun to recognize that their nationals abroad can be an important source of finance for development, as their remittances can cover family living expenses as well as investment for job creation. Migrants who return or circulate between sending and receiving countries can also be an important source of new technologies and ideas. When recruitment, remittances, and returns come together in a virtuous circle, as in the Indian IT sector, the result can be an important new export industry that also benefits those who did not migrate.
124. The ambition and drive that motivates people to migrate generally helps migrants in many countries to find jobs, work hard, and benefit both themselves and host country nationals. In most cases, migrants have only slight negative effects on the wages of nationals, and they usually pay more in taxes than they receive in tax-supported services. There is also little evidence that migration leads to much displacement of nationals in employment.
125. Finally, demographic trends in some regions suggest that immigration will be an important component of a long-term solution to the anticipated problems raised by ageing. Along with raising labour productivity and increasing labour force participation
-
especially among older workers -
countries will need to consider more immigration if a decline in levels of welfare is to be avoided. Promoting consensus on these long-term issues is clearly the task of responsible political leadership, since immigration always imposes social adaptation which must be supported by appropriate public policy. |
