The question is not so much about salary but accountability. A university is a national asset not to be run like one's garage. If there is transparency, there is no problem who earns what. There should be a system applicable to everyone so any Ram, Shyam or Hanuman can earn the same pay Bhadraman is earning. We should not assume that one is entitled to life time of pay off for creating anything especially when a public institution is concernced because it is getting fees and donations in the name of Nepal.
