Brain Drain
1.Brain drain is a phenomenon under which"people of a nation move to another nation due to financial benefits and also due to economical reasons,but there are many more reasons behind it". If we think deeply to the topic,we would find that this phenomenon has more disadvantages than advantages.
2.This phenomenon has many advantages for receiving countries which will automatically benefit from the skills and talents of immigrated people who were educated and qualified in their home countnes.
3.However,developing countries are deeply affected by this phenomenon since they are deprived from millions of their skilled workers, doctors,hardworking Engineers,and billions of man power. Those elites represent the backbone of their economies and once they travel abroad,their economies will not flourish and promote.In fact,there are many reasons behind brain drain.Firstly,the Government is the first responsible for brain drain. The salaries paid by local companies are much less than multinational foreign companies,which pushes millions of intelligent,hardworking Engineers to leave their native countries to look for a better life and opportunities.Secondly,the status and facilities provided by foreign companies are much higher in quality and quantity.Also,some people find it a matter of pride and dignity to work as an employee in foreign countries.
4.But we have to mention that brain drain does not only affect developing countries but also has some advantages for them.People living abroad help foreigners to know about their cultures and traditions.Also,they give information about various natural beauties and tourist spots in their home countries,which encourages tourists to visit them. This in turn increases tourist income.Brain drain also helps in increasing their foreign exchanges.
5.But at last you would find that brain drain has more disadvantages than advantages on developing or poor countries.So,to stop brain drain,local governments should make people aware of its harmful effects.Also Government should provide opportunities to their elites and should provide them with handsome salary so that they can serve their own mother nation.
This phenomenon has many advantages for receiving countries which will benefit from the skills and talents of______.
A.its harmful effects
B.immigrated people
C.the local government
D.their cultures and traditions
E.the hardworking engineers
F.in quality and quantity
