Until we can match the cheap labor of ,Taiwan, China and other third world countries. We wont be manufacturing many things like that over here.
Chinese worker lets say he makes $ 4 an hour ( lets be generous) no health, no dental, no retirement benefits nothing. He plugs away making ipads on a like and happy to even have a job.
Now the american worker I want $30 an hour and I want 2 weeks vacation, medical dental. I want paid sick days. He gripes about his job as he plugs away putting ipads together.
Where do you think many businesses want to have their factories at for the most profit. Thats why we dont build many things in the US.
