I don't think so. There are many very rich Chinese and Taiwanese who got
that way by owning factories, not by working in them.
If a Chinese factory pays US$100/week for a 60 hour week for
semi-skilled assembly work, a $3 product might have 50 cents worth of
labour. The 7% gross margin of 20 cents looks pretty good if there is an
order for 100,000 units, which is just 3 days production in a factory
with 1000 workers. Potential yearly gross profit: US$2 million.
