Can that one guy just STOP screaming 'troll!' on every thread? Gets bloody annoying! The OP's question seems genuine.
I doubt its an 'Indian' or a 'Chinese' problem though, but rather an Asian problem. Check out suicide rates among students in Asia and we definitely have way higher rates than the West in general. Be it Japan, India, Singapore, China as opposed to the USA, Australia etc. I knew this was a huge problem in Japan a decade ago, didn't know India and China took over. Anyhow, I believe the root cause stems from the fact that our Asian cultures enforce this concept of 'expectations' on our kids. They are expected to behave in a certain way, score certain results, read certain courses at college (even if they have no interest in it, they do it because daddy said so) and ultimately, adopt a career deemed acceptable to his family and circle. Anything short of this is met with disapproval and the person is deemed a failure. Asian parents tend to script every little detail in the lives of their little ones alot more than Western parents do.
Also not forgetting, most of the education systems we have in Asia tend to focus alot more on rote-learning designed at turning out robots than actual thinkers. Everything is about scoring the results at the big exams and failure to do so would usually mean the person's dreams (and that of his parents/family) would be shattered. Those who choose the coward's way out, tend to be those who have difficulty dealing with setbacks such as this. They'd rather not go back and tell those waiting at home "Hey, u know what? I didn't make it."
