Beliefs won't get you anywhere.
Boeing was a great company back in the 1950s/60s/70s, but they somehow just settled on their fame and good sales instead of pushing forward the development of new commercial aircraft. So this was Airbus' chance and they got their fair share of the market.
Nothing against you, I just want make a point about that.
Long ago, the U.S. quit using F-4 Phantoms, as they decided the airframe was too old and couldn't handle anything they wanted to do. Why use an F4 when you have F-18's and F-15's? So Isreal, using their brains, ordered many modified F-4's from Boeing. These came really cheap, cause it is outdated right? They ordered them with no engoines or avionics, had a canard on the nose, and a few other structural changes. When they got the airframes, they installed their own avionics (best in the world), and had the engines from an F-15 installed also. What did this accomplish? The Isreali Air Force now has an aircraft that can perform about 90% of what an F-15 can do, for about 1/10th the cost. So for the same cost, they can have 10 F-4's that do 90% each of one of our F-15's.
Just because some of the aircraft are older, does not mean they have served their life, it just means they are a proven design that can still compete. Why make something that is only 10% better that costs twice as much and required an entire revamping of operations, maintenance and logistical systems?
And yes, beliefs will get me somewhere, if I didn't believe I was an American Citizen, what good would I be? But I won't say anything specific about you in this post, I'll just state what I believe to be facts. (ie. the government says Lee Harvey Oswald killed JFK.....)
