I am not sure that we are not about to be surprised by a lot of Latin America. I note that one of the world’s top aircraft manufacturers is Embraer of Brazil. When I fly United from Mexico to the States, it is aboard an Embraer 145.
The IQist explanation is that Embraer’s engineers are all of the white elite, or, so help me, that “only the smartest Brazilians work for Embraer.”
This latter suggests that Airbus and Boeing use ordinary citizens, perhaps recruited from a bus station.
