But What I don't see is , What sectors the revenue of Nepal is being generated?

First federal budget aims 8pc growth Focuses on energy, infrastructure and proposes a string of reforms in social and agriculture sectors

I would like to suggest Nepal Govt. to generate self income by establishing its own factories in Nepal , generating employment 
opportunities in Nepal.
We ought to produce our own bike , cars and other machinery. These things are of high demands and use in Nepal at present.

Raising literacy rates without proper placement doesn't solve problems in country.

Instead of raising taxes ;    Raise peoples income, opportunities, jobs, living standards, Intellectual capability, Raise new Investments, Factories , establishments etc. When People will earn more , they will pay as per ability willingly.
