What exactly do you mean? All the major US tech companies (and plenty of minor ones as well) have huge India offices. If they were delivering "pretty poor results", they wouldn't still be operating.
I can't speak for all major US tech companies, but I can speak for my experience at a major US financial firm, household name, etc. A couple years ago they did the old dump the American devs and move everything to India. I'm the American team lead. The difference, as far as I can tell, is that the time to market for new features has doubled or tripled. This isn't because the Indian devs/QA are lower quality, they're about the same. The cause for all our problems is communication barriers and the time zone problems. All of our customers are in the US. Every single question that goes in either direction takes at least a 24 hour turnaround. God forbid there's some confusion, then there's 2-3 back and forths with a 24-hour turnaround each time until someone decides they're willing to stay up until midnight to have a phone conversation. Not having seen the books I assume this looks a lot better on paper. Where it will hurt is is ten years down the road when our lack of velocity/innovation catches up to us and a more agile competitor eats us alive. If we were in a faster moving market (consumer finance is pretty slow) that ten year timeline would be much faster.
I'm genuinely sorry about your situation. It seems like this is one of those cases in which management couldn't resist the short-term cost savings. I would wager this is a pretty common occurrence and I can see where you're coming from...and I completely agree. In this case its most likely not going to work out in the long term.
It actually doesn't bother me at all. In my younger days I cared a lot more about working on exciting/interesting projects. Now I care most about the fact that I'm 100% telecommute and have 6 weeks of vacation. Others may have had a different experience, but years of consulting have taught me to divorce myself from being emotionally attached to clients. I go in, give them my best advice and work, then go home. If they shoot themselves in the foot, then that's on them.
Working in a (top-50) Fortune 500 company, not tech but in the IT dept: we did outsourcing, CIO and top guys got huge bonuses, now we do in-sourcing to be able to operate. Last CIO recently fired. Entire teams of people based in India, Costa Rica or Manila closed, the skills and productivity are simply not good enough.
