Is American aviation going downhill?

I’ve been thinking that US aviation is really going downill badly recently with badly run and technically flawed programs such as the F-22, F-35A, B and C, Dreamliner, Super Hornet, Boeing tankers and on top of that the USAF fall back option, their 4th gen fighters, are all thoroughly outclassed by Euro canards etc etc.
Add to this that when the Meteor comes online the US will no longer have the A-A missile monopoly and the rest of the world has now learnt how to design and manufacture low observable warplanes ending the US ‘stealth’ dominance, worse still the foreign stealth fighters will probably work unlike the US jets with their laundry list of show-stopping technicial issues.

All that money available to the US and yet its all gone so very wrong, why is this?
