Question

explain how brain drain has also the positive effect

Answer 1

Advantages of Brain drain:

It allows excess number of highly skilled people to find well paying job opportunities outside their native country. That way other skilled people of the native country will find opportunities in their own nation. This is particularly true in India. About a couple of decades before, there were a lot of highly educated but jobless people. With some of them having gone outside of India for work, the locals are able to get that work. This way, it helps reduce the percentage of jobless people in India.

The income from the emigrated people comes back to the native country as overseas remittances. India is recipient of the highest amount of foreign currency coming in as remittances from NRIs.

It helps improve the education and infrastructure in the native country, which in turn develops country further, because the native country realizes the value of well educated people. In India, it helped spur the growth of software education.
