Opportunity in Adversity?

Japan is experiencing nothing less than a tragedy. Is capitalizing on it and trying to replace their damaged industries inexcusably cold hearted or good business?

I was just reading how GM is shutting a plant in Louisiana due to a shortage of Japanese parts. This is bad news for the Louisiana economy and the people put out of work. It also represents an excellent opportunity for other machine shops and job creation for someone to replace the Japanese parts and re-open the GM Plant.

However, it could also be considered kicking, so far as I know, a nice country full of good people while they're down. Really down. Ofcourse, there are really nice people all over the world who need work.

What do you all think? Should businesses be taking advantage of a competitor's, even an entire country's, misfortune?
