Well some of them died. Krishna Bhattrai, Ghirijha Koirala, Ganesh Man . World wide life expectancy is around 78 and nepal is around 71. Some of the current leader will for sure die in next few years . But that won’t be solution. Nothing changed when it went from Ghirijha to sher Bahadur. Nepal is fertile ground for useless and corrupt leaders and burocracts . It will produce many more and most likely even more corrupt.

Nothing will fix until nepal society and education system is fixed . Cultivation on land is fallout of type/property/weather of land not plant itself.
