That's funny! That's why their operating income is a massive 5.88% of revenues.
For the nonce, try looking up and then reading on the actual production costs of mass-produced items (including processed foodstuffs), and the mark-ups along the way for transport, shipping, middlemen, and the like.
The savings from going overseas are the lower wage scales, lack of environmental regulations, and the like; the physics and chemistry of the production processes are identical.
Cheers!
