These facilities are expensive, like 20-30B for the big ones. If you’re curious youtube has some good long videos on how these places work. As far as I’ve checked all the gov grants given to companies as incentives (whether chips or energy or other infrastructure projects) only partially cover the costs of construction.

But then US interference most directly affects US jobs and customers. That’s a much better er situation.

Think of car manufacturers that have done this for decades. They may have a global supply chain, heading mostly back to their home country, but they also have worldwide plants near their customers. Thanks partly to similar incentives and tariffs, my Honda was assembled in, I think, Kentucky, and was as us-manufactured as any us brand, meaning us jobs, us manufacturing, partial us supply chain. The result has been almost entirely good.
