P.S. Don't think that when that plant in PA is shut down that those 100+ workers were replaced by 500+ chineese.
Chances are the new factory in China only has 50+ people running state-of-the-art (finaced by the state) computerized machines that simply take the CAD file that was mailed over and spits out the mold.
China has lost more manufacturing jobs as a percentage of population than the US.
Just like when the US lost the steel industry to Japan. It wasn't the cheap labor, tho that was in the mix, it was that when Japan was rebuilt after WWII they had all brand new state-of-the-art furnaces and could make better steel with cheaper cost of materials/fuels than the 100 year old US furnaces/foundarys.
Now we are finding this to be true for other upstarts without the baggage of older machines and near-sighted management not willing to retool the factories because it will cause the stock to take a hit while they rebuild... Solution... Rebuild some place else... New factory better and faster than older factory... Close the older factory...
