Delta shifting away from call centers in India

Yesterday, we posted this podcast which looked at why customers are often treated badly. One company is starting to listen to their customers. According to Bloomberg, Delta has begun to shift their call centers out of India at request of their customers. They've moved these call center jobs back to the US.
Do you think the shift of call center jobs back to the United States is inevitable? Will American customers become more loyal if they reach someone on the other end of the phone from America?
