"CHINA" Christmas

I started this thread due to frustration. I work in the road construction equipment industry, we are having a very tough time getting parts for repairs. It's not just one manufacture, it's everyone. The reason is, America doesn't have any manufacturing abilty like it had in the 50's, 60's, & early 70's.
Everything is being outsourced & Mfr's are not stocking their warehouses. This creates a delay for parts. Just try telling MR. customer, that his $150,000.00 Excavator has to set foe two months until the part comes off backorder. This is all done in the name of profit.
I believe in capitolism, but when is enough profit really enough.
The thing that I don't understand is, if it only cost $10.00 (outsourced) to make a pair of shoes, why do we American's willing pay $150.00 for them?
What happens when the middle class does go away? Is the other 10% of the rich going to keep corparate America profitable?
With that off my chest, I had a very great Christmas & wouldn't trade living anywhere else.
