I think you misread my point. My point regarding NAFTA was that US did not actually lose a portion of its economic output when the manufacturing declined. The old factory workers switched to a more profitable job, thus the income increase. In fact, the country was then joined by migrant workers from Mexico because of NAFTA taking away their farming jobs in Mexico. Thus US's economy thrived in 90s.

But when China lose most of the foreign manufacturing jobs, it lost a significant portion of its economic output. Because now these workers just went back home to countryside to farm.
