That's the whole point... The money is in the United States not Europe
The two are connected. American airlines purchase much from Airbus, Canadian, even Brazils airplane industry. That and usually the worlds aviation industry either profits or suffers as a whole. Theres a crapload of people in the world who want to get from A to B, orders are booming for new passenger jets, new markets are emerging. So again I ask, Whats wrong with it?
