I heard, in South Korea, personal income tax is less for Masters... and significantly less for candidates with Ph.D. No wonder, Samsung (South Korean Electronics Giant), over 10 years -- increased Doctors (Ph.D.) by 5.5X (@ 300/year!), while regular employees increased by only 2X.
Below is the data from news item (How to grow an electronics giant - from http://www.eetasia.com/ - posted 17/Nov/2008)
M.Tech. takes 2-years, Ph.D. takes ~4-years...
After M.Tech. or Ph.D., candidates get lesser designation (less by ~1-2 years) compared to their classmates, in a given industry (Except for Research positions... very less in openings India... very high in demand... very difficult to fill... a paradox...)
Going for M.Tech. - understood - it is only 2-years... not a big issue (earning a livelihood for family (=parents)) for many....
Going for Ph.D. - the trouble factor - it is 4-years... a big issue for many... time to settle down and get married... without earning - it is very difficult in India... (may be exception for rich families... or for candidates very enthusiastic in higher education).
So, where is the incentive for Indian students for higher education?
Without having technology creation by research, we will be doing only technology-service... this is called service economy... this is not knowledge economy...
A country boasting "knowledge economy" - meaning sell your knowledge as service, for others to create products, and sell products to you?
