No one has right to tell others what to do with their money. Period. 

I am all for those people who want to make Pashupatinath/Swayambhu here in USA. I am also glad that people teach their kids our culture, our language here, and continue their connection back home.

We can always raise questions such as following:

Some of you may drink alcohol. Have you ever thought of giving that money back to nepali poors?

Some of you may have gone to restaurant. Have you ever thought of making food at home, and donating the saved money to HeNN Nepal or some charitable organization?

..

.. 

etc. etc.

But the fact is we all do what we like to do, what we think is more important to do. At this moment, may be a lot of Nepali think it is important to make a slice of Pashupatinath here in the states. All power to them, and there is nothing wrong with that. 

Similarly, may be several of them thought Nepaliko lash need not be taken back to Nepal; it is just unnecessary hassle. Or may be some of them thought the parents who could send the kid to the states may have enough money to foot for such bill themselves. In any case, there are thousands of needy people in this world, and people prioritize their charity in their own way. Nobody has the rights to tell others what to do with their money.

Let's have positive attitude.
