@nick > But the difference is that the US incentives are domestic, and designed to nurture development within the US's borders.

this is a fallacy. Any time you do tariffs or grants/subsidies to make "American products" more affordable to prevent foreign products from becoming dominant in the market you are stealing from Americans. When the consumer can get products for less they have more money leftover to spend in the economy and boost other businesses. These tactics look good from a distance but are actually an invisible tax on all Americans under the guise of "saving an industry".
