That is only looking at (mostly orbital) launch systems, such a minor part of NASA's R&D and missions that the Obama administration decided to contract it out.
NASA doesn't develop or build lots of technology that has become mature enough that private industry can take it on and NASA can focus on the past-the-bleeding-edge stuff.
Their explorer robotics are interesting, something I would be proud to work on; but a pretty different nitch.
So NASA is not drawing from the best people anymore.
