My point is that as a taxpayer in Germany, I don't want to subsize an American company. Better to invest in local companies like Infineon or Bosch.
Mercedes got $260m in Alabama in the early 1990s, BMW got $150m in South Carolina in the early 1990s, Volkswagen got $570m in the late 2000s in Tennessee. That's close to $1.6 billion inflation adjusted from just three examples of it.
The US economy is six times the size of Germany's economy, so those are massive subsidies in relation.
