Again, it's not trade that is the cause of our slow economic growth. You've shown no correlation for that. Businesses have moved basic manufacturing jobs off shore because it makes economic sense. You can call it greed but it's what businesses have been doing since the beginning of time.
And yes technology/automation had done away with numerous manufacturing jobs and will continue to do so as we build robots that can do more, driverless cars etc.
We aren't going back to a time when a guy with a high school diploma only goes and works in a factory for 30 years and lives a middle class lifestyle. In the Information Age knowledge is king.
Why not?
There are still factories they could work in. We have just moved them all to China, Mexico etc. Those are factories that could be here instead so people coming out of high school could go to work in.
Even the most technologically advanced businesses in the world (such as Apple I gave as an example) still have manufacturing plants that use
people (not just robots) to manufacture their products. They are just all in China instead of America so they can pay those workers less. So the robot argument doesn't hold much weight with me.
I am very familiar with how products are manufactured today. And while yes - automation and machines are used - there is still a great many amount of people who are still needed to operate and repair those machines. Factories do not move to China and Mexico because there are more robots there.
You think it makes economic sense to offshore our manufacturing sector. But the stats don't agree with you. These policies have not been growing our economy. They have done the opposite.
