At the expense of American's losing their jobs? I'm guessing you've never had to go home and explain to your family why you got laid off. I have. Not fun. America became THE world leader it is because of it's manufacturing prowess over the last 100 years. We can't live on a service based industry forever. I'll pay you to fix my plumbing and you pay me to fix your furnace. Its not easy changing professions when you are upper middle aged and can't afford to cut your pay in half to start learning another trade.
The original post about made in China on the side post castings can be summed up in a few sentences. American iron casters for a long period stuck together and kept their prices up at a profit while machine shops slashed their prices to keep the doors open hoping for sunnier days. Deere and many other major players cut costs by going to China. This transferred the environmental byproduct overseas. But the local byproduct is many, many families displaced by unemployment.
Global Macroeconomics is a very dynamic subject. One of the major problems about trading with China that I haven't seen brought up yet is the fact that they keep the value of their currency low. This is done through a complicated means. They want to keep their products cheap to us and our products expensive to their consumers. If they allowed their currency to float on the world market like the rest of us do, it could mean their products could double or triple in cost putting them on par with many of ours. They CAN'T let this happen due to their economic goals.
I keep seeing references to Japan and how we "brought them along up to where they are". Well, Japan is a drop in the bucket compared to China. Bringing China up to par will bankrupt us. Japan learned early on (from an American none the least) that quality is where its at. They adopted it as a country, not just as a single facility.
There are machine shops closing across America on a weekly basis.
