It's a bit more complicated than you might think. What does "Made in America" really mean? If by that you mean "all the parts were put into the case in the US", then that really doesn't bring a lot of wealth creation into the nation - most of the money still goes overseas.
If you mean "Chassis assembly + fabrication of the circuit boards", that still doesn't add much to the US economy - stuffing circuit boards doesn't take "labor" (as in "humans working"), it just takes time on the pick-and-place machine.
If you mean "Chassis assembly + board fabrication + components themselves built in the US", then you are starting to talk about a meaningful amount of wealth creation brought back into our country. Of course, now not only are you wanting Samsung to build plants here, you are wanting all the various chip vendors, the makers of the LCD panels, the passive component vendors (resistors/capacitors/inductors etc.), and so on to build plants here. Again, that would be great for the US economy. It would ALSO cost hundreds of billions for the companies to do.
That isn't going to add "a few dollars" to your TV - that is going to add thousands of dollars.
I work for an electronics manufacturer. We still do a lot of work right here in the US. But all the components we use to build our stuff are built overseas, because there are no US fabs for them.
You don't like that? Write the people who made it happen - your Congresscritters.
Would anyone here be willing to pay a few extra dollars for their LCD if they know American workers actually built it? I realize Samsung is not an American company. But, I would personally pay more for a good quality TV (even if it is not an American brand name) if I knew it was made in the US then buy a American brand that was made else ware.
Does anyone else share my feelings?
