"most of the flat-screen TVs sold in the United States, from companies like Samsung and Sony, are made there, along with everything from medical devices to aerospace parts."
Not sure about medical devices or aerospace parts, but one of the reasons those float-screen TVs are "made" there is the tax advantage. They were mostly made in Asia and the final assembly was done in Mexico.
I believe the Maquiladora principle is that Mexico doesn't charge import taxes if the finished product is for export. So components come in from Asia, get put together, and pushed out as a finished TV.

Still, you have to start from somewhere.
