Why Does Manufacturing matter?
Manufacturing is important to us here in the U.S. for multiple reasons.  First and foremost it provides our country with high-wage jobs.  It also creates commercial innovation, a trade deficit reduction, and also contributes to environmental sustainability.  The manufacturers that will have the greatest chance of expanding employment in the U.S. are the those who do the following:

1.        Computers and Electronics

2.       Chemicals

3.       Transportation Equipment

4.       Machinery

Productivity and wages
These vary greatly depending on which industry you are in.  Many top ranking manufacturers in order to produce a higher level of performance hire skilled workers for a respectable wage.  Unfortunately the U.S. falls short to outsourcing manufacturing compared to other counties, mainly because of the laws that are in place to protect the wages of Americans.
