Do what you do best and outsource the rest.

It's a principle that has been around forever and it is really true. Boeing is a systems integrator. They take multiple parts and turn it into a major system platform. It's much better to have companies who are experts at turning out certain pieces (airframe, wings, whatever components) manufacture and deliver them to Boeing, rather than Boeing (who is a good integrator, but maybe not an expert at manufacturing certain pieces) do it.

That comment about all the problem coming from subcontractors is just some union wrench turner who is mad because his overpaid union job got outsourced to someone who can do it cheaper and better.

Labor unions need to be careful to not set their wages outside of what the market will bear, otherwise their jobs will go away. The UAW is a perfect example. Unions should be there to support their employee's, not demand ridiculous wages.
