It's virtually impossible to address a social ill without the society first acknowledging it for what it is. When the education system does NOT do that, what chance is there at all of there even being a discourse about it, forget take steps to address it?! That is the situation with the caste system in Nepal.
Nepali society is highly dysfunctional, hollow, and deeply flawed. There are many reasons behind that.
One is that Nepalis struggle greatly to empathize with fellow Nepalis even while they take pride in being born in the same country as the historical Buddha.
Another is that accountability for one's words and actions are virtually nonexistent. The reason? The level of education of the population is low, and even that education is of poor quality, the products of which are people unable to think and reason logically.
I have come to the conclusion that Nepalis in general struggle to empathize with fellow Nepalis who are, for example, suffering for whatever reason. The reason behind that is their low power of imagination.
Why are their power of imagination low? Caste system induced attitude, lack of travel experience, poor quality of both formal and informal education, and lack of reading culture.
From 1990 onwards, we've has a competition in Nepal...a competition among educators to give their academic institution the MOST ridiculous and/or absurd name. I know because, noticing it, I did a write-up on it and even stalked about it in my FM radio program in 1998. So, after three decades, who is winning? All of them...and naturally education is losing out.
