One of the fields that isn't true is civilian aerospace. Innovation cycles are long, regardless of country, regulations are more or less the same. Nobody only certifies according to EASA or FAA, everyone does both. And with Airbus and Boeing forming a duopoloy on civilian aircraft, both sides have equal interest, and funding, for innovation.

Throw in all the current eVtol start-ups and I don't see that much difference between the US and Europe.
