Total BS. The amount of labor that goes into each manufactured product varies but it averages around 6-7%. Using slave labor saves around 3% and reduced taxation / regulations saves maybe another 2% per unit. So your numbers are really bogus; if not laughable. So off shoring saves the customer 1 or 2 % with the other 5% going to shareholders and CEO perks.

You anti-free trade fools are really anti-liberty. The problem isn’t free trade, but government. Capisce?
