Indian Gujarati here, so I get a pass for what I'm about to write.

If this article was about whites or about Christians, it would not have a laudatory tone. Instead, the author would be writing about how the "old boys network" keeps others out of lucrative businesses, about how there's no diversity in the top rungs of these companies, and about how "handshakes" are circumventing government laws and taxation. But that is exactly what the Gujarati network is all about. Yes, it is a hardworking group, but also very in-group oriented, and yes, racist.
