Nice narration, well done. I think most of us share your sentiments to the extent of our own experiences.

Not as an intention to take the focus away from your writing - some thoughts come to mind on the following given that there are many of us who, most likely, have similar dislikes:

"However, I still struggle to understand how can we speak of justifying actions of nepalese leaders, speak of terminating the poverty, or build infrastructures in Nepal at ANA or during gatherings when are main focus is to eat, drink and be merry."

This, admittedly, had been the norm for some of us for so long - however, we have begun to sway away from these organizations to tackle a few of the issues you mention quietly on our own individual merit. Maybe you can follow suit? An example of this is to get involved in the area where you have the greatest experiences and qualifications - and directly contribute in hopes of uplifting the entity, even just a few percentage points is enough, with a positive impact. These set-ups or partnerships work nicely when both you and the entity benefits, however. 

Not to boast about it - but to just to give you an idea - I have recently agreed to volunteer to lecture at a local college in an area I have worked for years. I am also in touch with the stakeholders (mostly government officials and business sector players) to drastically improve foundational underpinnings in-par with the standard and regulations (seen mostly in developed countries) required for the industry to operate as a self-functioning entity. Whether it comes to fruition is another story - but having the chance to give back and work through the issues and processes is nonetheless a privilege, as opposed to an opportunity.
