Luckily for Indian men working in America, they will have absolutely no problem getting an arranged marriage in India.
Guy I work with is a 37-y.o. Indian American (his folks were immigrants). His parents got him into an arranged marriage with a girl in India he had never met in person. Arranged marriages are the norm in India.
I don't think Indian (or other South Asian) men have a problem getting hitched. The problem is with Oriental (i.e. yellow-skinned) men. Indian men get hitched back home because that's what's expected of them. They could equally find Indian women to marry in the US on their own, but are far more traditional than Oriental men. So they obey their parents.
How do you figure that Indians are far more traditional than Orientals? The same way you do in the Mid East. Just how often do you see people dressed in native costume in the Mid East and India? Very often. And how often in the Far East? Just about never. They dress just like Westerners, except perhaps a little less casually.
Romantic love is simply not part of the Indian tradition. It isn't part of the Oriental tradition either, but has been absorbed from the West along with other Western customs like monogamous marriage and Western dress. India has done a much better job of preserving its age-old traditions. Which is why things like arranged marriages continue to be a fact of Indian life.
