We are misunderstanding the biggest and the simplest factor. Democracy will not work in a culture like ours. We have too many rudimentary flaws in our social system.
Social Reform first
then Political reform comes later.

Not the other way around. Every developed country went through social changes and then later came the political aspect. We on the other hand are going the reverse, it simply will not work.No other nation has done it. We'll never find "a dynamic, charismatic, bold and brave individual".
Why do you think we have a expression "Jun Jogi Ayepani..." cause it eventually happen no matter who get to the power. Our forefather knew it, so they made it. Can you translate the same Nepali saying in English? Do they have something exact like that? They is no concept like that....everybody will NOT be the same, is what they believe in and comes out pretty true.
"Birds of a fether..." is not like ours.
All these so called F##d up leaders are just ordinary people like you and me, have family who love and support them,role model for relatives, their crooked power and wealth are raved by the neighbors,neighbors--- who are cursing at their straight son for not being a successful crook. How many parents do that in the West? How many parents say "I wish you were like OJ Simpson"
Values! Values! Values.
My 2 cents.
