A person who get's assisted all the time will never learn to do anything himself/herself. I have seen this personally among kids of rich parents who never had to raise a finger to get things done because it was done for them. When time came to do something by their own, they had no idea where and how to start.
Same is true for Nepal. Nepalese leaders always find ways to ask for grants and loans from other countries. Thus they never learn to do anything for the country.
