Who knows how much it is exactly. China Production is at least 10 times more than is showed in your stats, as this is posted in dollars but China produces in their currency which is undervalued by a factor of 50 as China can pay workers .20 cents an hour. In a free market prices would even out and workers would make about the same . that they don't shows the rate at which China manipulates its currency. Fact is U.S. workers get paid 50 times more than China factory workers but it should be about the same if the marker were free.
FACT is China makes 54% of the world's steel and most of the electronics 9 billion people use. U.S. makes no consumer electronics not even our own.
