The waste in acquisition programs dwarfs any and all end of FY spendex. It's not even close.
You're probably right, but just from an "industry perspective":
Increasingly, industry seems to have been asked to "build us something that includes 5 or 6 sequential miracles"...at an affordable, well-defined and predictable cost. YOU assume all the risk when the miracles don't shake out as expected. We'll hammer you if there's any cost growth, and blame it on industry.
Examples:
LCS: Hey, Mr. Industry, Please sign a contract to build low-cost "sea frames" designed to "commercial standards", and then "BOHICA" when we tell you, after the fact, that commercial standards won't meet service/congressional scrutiny, so then go and do it all over to make sure your sea frames meet "Naval Shipbuilding Standards". On YOUR dime. You should have known better, after all...and, while you're at it, design these ships to be fully capable of operating/integrating three as-yet undesigned and undefined "mission modules", each of which will come with its own assembly of as yet undesigned/undefined UAVs, interface challenges, manning issues, etc.).
JSF: Hey, Mr. Industry, we want an airplane that includes, and relies upon, dozens of technologies (stealth, supersonic, STOVL capability (in addition to conventional and CTOL variants, of course...each with their own objective/threshold requirements, like range, payload, landing weight and speed, etc.), composites and other materials fabrication, sensors, integration, HMI, helmet-cuing systems, shipboard interface, maintenance, security concerns, life-cycle costs, etc.) that don't yet exist and we want it "on time and on budget". You figure it out. When "concurrent development" costs go crazy...well, what do you have to say for yourself?
Presidential Helo: Hey, Mr. Industry, please propose a cost-effective "replacement" for the current fleet of HMX-1 "legacy" airframes. After we get your signature on the dotted line, please include almost every single capability that currently resides on Air Force ONE, to include nuclear weapons-secure comms, worldwide comms, full VTC and MILSPEC SIPR capability, full galley, POTUS-appropriate "suite" and other creature comfort features...well, you get the idea. What? You didn't read between the lines in the procurement offering? What are you...a child?
I'm sure there are more.
