Probably in the U.S.
As were most of any profits taken from any plant-closing. The U.S. remains the most profitable venue in the world for investment.

Don't go all Pat Buchanan on us...
I do realise beyond any doubt that capitalism is the only system that ever has really worked. This remains true and probably because of human nature will always be the case. The shrinking middle class,though, must be addressed. Service jobs will not do this. Green manufacturing jobs will not either. We need value added jobs such as manufacturing and mining.
I realise that modern environmental regulation make this all but impossible, so it is not the fault of corporations for the most past. It seems though my original statement bears some truth. Example: G.E. lighting Division in N.C. has always been a profitable division. There was an attempt to relocate production to Mexico.Because the quality could not be achieved there the Mexican plant production was put on hold.This was money and jobs to be taken from a small community. There were no plans to reinvest anything in that community. Unbridled capitalism gave us the Love Canal and sometimes worse.
