The reason why Aegis has opted to hire locals within US is for their native American accent. The cost of vocal training of an average Indian employee is quite high. Given the attrition rate and gap in quality of delivered service, it makes sense for these companies to find out ways to sustain and meet standards. That's why cheap hire of people who "lack high school diplomas" makes sense in the US.
This does not in anyway suggest that India is now 'outsourcing' back to United States. That is likely to happen only after huge and reverse tilting between the two economies [Assuming China does not exist!]. IMO, this move on part of the company indicates only their incapacity to serve from India. In other words the article is just an ego-massage fluff piece.
