This is just the beginning. In addition to call centres relocating to India, IT and engineering positions are relocating too. In the long run USA will be de-skilling their workforce. When USA has fewer individuals with these skills, the cost in India can increase and USA and other advanced countries will have no option but to foot the extra bill. In the end, India will be a world leader in high skilled areas with the vast experience gained.
Don't rule out the option to move back ???.
