I think it’s very easy to explain. The US are some of the worlds greatest sellers of intellectual property which makes for better business, since you only need to invent something once and then you can sell it over and over. The US would prefer to spend it’s time doing more lucrative work.

I don’t even think it’s very clear that recent US efforts to onshore manufacturing, both broadly and within green energy specifically, are even helping it. The US is paying close to a million in extra costs for every job it’s on-shoring, although there is the benefit of improving the US negotiating position and military readiness beyond bolstering employment.
