Why do Indian student go abroad in search of opportunities

Post graduate students from India are increasingly choosing to study Abroad. Reasons for the departure why? There's no doubt,many reasons,why indians are choosing to study abroad. Two of the factors are low quality programmes and low seats. When bright students look around India for a place to study for an advance degree they find few top quality programmes.In the field of social science and humanities there are small no of respectable departments,but none of them are  considered by international experts.
There are many institutes such as Indian institute of technology , The all Indian national instutute of medical science, The Tata institue of fundamental resarch.
But number of student who can be served by these  institutions are quite limited.

Thus, if a bright Indian wants to study  for a doctorate or even a master degree he / she is forced to study overseas. Further,a degree from a top foriegn university Tends to be valued more in Indian joy market than a local degree.

According to a research , India's population living abroad is the largest in the world with 1.6 crore

So the question rises that how can we improve our education system.

The main role in this is of the government because it's the govt. Which provides funds  to the colleges and universities for the proper infrastructure and education material.

But somehow these funds are not reaching to our colleges or any institutes and as a result teacher goes for strike for not getting salary. And the education of the child suffers.

This is the main difference why education in foreign countries is much advanced than education in India.

Our govt, should put more efforts in building good colleges and universities than acting upon the issues such as padmavat etc.

If govt. Would be fare to institutes there will be more opportunities and students will no go abroad in search of opportunities
