2. That's probably true, but the US labour market is simultaneously huge, flexible, and well-educated. That gives it an advantage over most competitors.
If you put people in a situation where they can only produce crap, then that's what you'll get.
Legos are made out of petroleum
If the question was "what are Lego made of?" then this answer would at least make sense, but that's not what the question was.
For what it's worth, Lego has used a lot of different materials over the years, and not all of them have been petroleum based. To be fair, the majority of their new products are made from petroleum based plastics, including ABS (Acrylonitrile Butadiene Styrene), polypropylene, MABS (Methyl Methacrylate-Acrylonitrile-Butadiene-Styrene), PA (Polyamide, aka, nylon), POM (Polyoxymethylene), PE (Polyethylene), MTPO (Metallocene Thermoplastic Polyolefin), SEBS (Styrene-Ethylene-Butylene-Styrene, the material used for "rubber" tires and similar), and PET (Polyethylene Terephthalate).
There are efforts being made towards replacing ABS with recycled PET. Some kits may already use recycled PET.
* Does the cheaper energy come into play with such a large onsite solar system?
* (From the point of view of a manufacturing company opening operations in the us) Does the US currently have a surplus of well trained manufacturing workers? I hear a lot of factory management/executives still complaining that the skilled labor they need just doesn't exist.
