I have actual experience in this and can say its not as you describe. Usually the onus is on the Indias to conform to the US work schedule. Yes accents are difficult at times but not an insurmountable hurdle. We never predicated our project schedules to anything going on in India. Thats a management problem in the US not some defect w/ the foreign workers.
The biggest problem Ive seen is lack of competence. There are VERY few that are truly technically excellent and even fewer who are motivated to excel. The later just isnt part of their culture. In the end it makes the end product iffy at best. That said, if you carefully manage whats going on the outcome can be OK.
In the end the problem of displaced domestic s/w engineers is home grown. Poor management is the root of it.
Maybe where you worked but I had a weekly pre-7am meeting I had to attend to be there to talk with the team in India.
I have also had a person from a foreign (Swedish) tech firm tell me that their VP wanted someone without the Indian accent to communicate with him and above.
May be discriminatory, may be “atypical” but one was a place I personally worked and the other was a position I was told about by a contractor.
