I think any person who has done telemarketing from India can tell you that "white voice" is a real thing that makes a big difference. Working in a call center, you can really see the difference in how people treat you. I have worked in call centers in Canada, and we have a large Indian population here, and people will yell and scream and insult people who have an Indian accent, but they can call the guy next to him who is also Indian with no accent and say "finally I reached a real American!" (even though they are both Indian, and we are in Canada). I feel really bad for guys with thick Indian accents who have to work on the phone.
