Manufacture is important for the families involved, but there is another feature, that is really important regarding manufacture, that has to do with the competition with China.
China is actively undermining American and world economy by going directly against branches of industry.
One thing is, when American entrepreneurs and ‘developers’ like Mitt Romney, actively, sends good paying American jobs to China, another is, when China is ACTIVELY focusing on a branch of industry to take it from the West.
They do it by state subsidising specific branches of industry, and thereby dumping the prices.
This is industrial warfare, and should be met with equal measure.
G-d bless the will, to see where the danger lies, and counter it.
