Whose responsibility?

In the software development arena of Silicon Valley, off-shoring is a hot topic among developers. Often discussed with a sense of contempt, fear, and disdain, this reputation is not unwarranted. Business strategies for new software products are not considered complete unless an off-shoring alternative is included. Jobs are being sent overseas with increasing frequency as companies assess the potential savings.

Directors express tinges of guilt as they lament "we would have loved to keep the jobs in the US, but the cost savings is too great..." Who is really to "blame" here? Does a company owe anything to the country to keep jobs domestically, even if it incurs a greater cost? Is it the government's job to step in and do something? I've heard so many contrasting views, it's hard to determine which POV is "right".
