1) You mentioned doctors, for example. How many MD's are here on H1B visas? Remember? The medical industry covets shortages to drive up physician compensation.
2) Assimilating to the culture gives the game away. If the Indians were so superior, why didn't THEIR culture produce inventiveness, drive, and prodigious wealth? Back in the 1800's or so, India was wealthier than the US. And the US's "exploitation" was of blacks and (Cherokee, Sioux, Ojibwe, etc.) Indians, not Hindu (Hadji of Jonny Quest) Indians.
And you spelled "polysyllabic" as "polysylabic". Which brings up one more point. Too often Indians are praised despite being incomprehensible, and using language in emails which would get an American summarily FIRED on the spot. I thought business valued communication. It'd be nice to have the same standards about "being qualified" applied to all comers. :-) (Cheap shot, sure. But it's annoying to be lied to so blatantly by tech support. I am tempted to answer in a broad Texas drawl, "Y'awl, my name's Srikant, an' I gotta problem I ain't been able to solve, so I'm fixin' to ask some questions.")
Cheers!
2) Their culture does produce a lot of those things - probably in excess of that found in the United States. Part of their challenge is that much of the country is still very backwoods and they have had some pretty bad governments. And I never said anyone was superior.
As for grammar, I deal with people here all over the country on a daily basis as well as all over the world. I've never fired anyone on the spot for bad grammar. The Indians I deal with these days - here and in India - have grammar as good or better than mine or other Americans I work with.
