Actually, Boeing is probably just as heavily-subsidized as Airbus, though the subsidies are indirect. Just about all of Boeing's R&D costs for new technology are financed by contracts for military aircraft. Someone who knows more about this than me might be able to quantify this, but I would venture to guess that alomst all of the technology used in civilian aircraft was first used in military aircraft.

That's true, but R&D costs are out of the normal realm of doing business.
