HOWEVER.....

Do we count products made in the US from foreign parts as US made? What about products made in Malaysia from US materials and parts? Boycott either one and the US job market suffers as a result.

Where do they get their raw materials?

source chips? (Hitachi and Samsung control most of the memory chip production)

subassemblies?

Tracing where what comes from becomes a near impossibility.
