My college (im sure like many others) had a bunch of rich international students from India. I found them to be hard working, ambitious, and generally down to earth. Perhaps it was because they were well traveled and had a will to surpass their family's wealth with their own stamp on the world. Many had also done a lot more community service than American peers in much more squalid conditions...they also seemed to be more attune to their (screwed up) political system.

In short, just like the other comments, I don't think this rich kid ennui is just in India...or Delhi
