It would be immature to quetion his patriotism , when his cause overrides those boundaries......As long as he is doing it for a meaningful cause...for education...its great !!!
..besides...are you questioning the rich Indians back in india on what are they doing to equal what Kapoor did for US Universities ????

It is his money and he can do what ever he wants. He felt he owes it to this institute. I hope the institute remembers that and continue to support alien students as well as local students.
One question can be raised about all of who got educated in India, most of us were educated by Govt at no cost. That is service that mother India never aks us to pay back in any way. If mr. John Kapoor feels he owes it to UB, then logically he owes as much or more to Mother India that gave hm education in formative years and free college. It is not something a mother will ever demand, it is upto Mr. kapoor to do that. Well it applies to all of us. he may already be doing that. So I would not go around criticisizing him.
But if someone makes an argument that he owes more to UB than India, that argument is similar to Mother vs wife. Who is more important. My answer would be both should be given importance.
Many US universities do support alien students (a lot of Indian students). Cases in point: two of my nephews are in masters programs on scholarships at a SE university. Not only they are getting free education but also enough money for their food & apartment.
most of us have been graduate students and taught the undergraduates while getting paid a pittance. it works great for Indians and chinese because it is still a lot more than we coul;d command in India but it really works well for the university, which could only afford an average local brain at 3 times the salary.
Considering that best research is done by grad students and shared with many smart professors, the value of foreign students to USA economy and research was recognized shorly after 60s.
Since there are about 2 million -3millon Indians in USA, about a million make 100,000 or more and control assets worth about a million or more. If you are paid 100,000 then you must be producing about 300,000 for the employer of business.
thus assets controlled by Indian types in USA is 300,000 x 1000000 + ownership 1000000x1000000= something like E+12 or about a thousand billion. If Indians went to India with 1000 billion it would leave a black hole behind and inflicting a very serious loss on USA and very big gain for India. USA would not be destroyed but USA is now aware that Indians are useful and Jihadis are not.
Moral of the story is that wealth gained by an Indian, unless it is shipped to India would get spent finally by a city like Baltimore and contribute mostly to the well being of locals- so locals should rejoice that non- Christian brains, come from afar, put up with many travails and succeed in USA and raise the standard of living of locals.
This is unique to USA, everybody can suceed here, everybody knows it and wants to come to USA - very few great people like Bhaba, Sethana and a bunch of Parsis who can suceed anywhere returned to India and succeeded in India also and helped India and Indians.
I knwo that. I was one of those who benefited from US education. The key word is "continue to".
