Well, there was a time when students who came to the US were mostly on scholarship.  With infusion of relative affluence among Kathmandu community, the new breed of students are mostly self-financed to a degree.  

In the latter case, financing from home usually covers the first year and the student is expected to win scholarship or generate necessary funds through off-campus employment.    Now with stricter regulations, students are being forced to ask for funds from home more and more.  

Not all parents who send money to pay for their kid(s)' education are corrupt.  Some people have become really affluent in Kathmandu through legitimate means, believe it or not.  And there are those who are land rich.  Sure there are corrupt ones, especially those who work in public sector, but my point is, not everyone is corrupt.

So what I am doing here stating the obvious?  All I am trying to say is: to each his/her own, and it ain't nobody's beezwax.
