China can currently make stuff cheaper than the states can, because they are a society of slaves. That might not last forever, but while it is going on it creates chaos for the erstwhile US manufacturing base.
Of course the devils advocates need to be considered too. Let’s take the extreme case: if China could furnish everything we wanted, free, would we be foolish to refuse it?
The “value added” by manufacturing in a slavocracy like China is cheap labor. Every other cost is the same or even higher due to shipping. At most, we are throwing away our critical manufacturing base for pennies on the dollar. It is enough to make one cry.
