However, in 2020, India launched India International Skill Centres (IISCs).
Some of the information stated on their website is:
Government of India is keen to bridge the global shortage of labour force in the coming years by reaping the demographic dividend of young Indian labour force.
180 candidates [from IISC] placed (offline data)- 63 in overseas locations (35% of total placement), 117 in domestic locations (65% of total placement)
Prima facie, this looks like the government is aiding brain drain - that is, a bad policy decision. But the program continues, so there must be some benefit.
Why would the government of India invest in creating skilled labor, and then send them to work overseas? How is this advantageous for India? Has the government explained what they hope to gain from this?
