A problem with analysis like this is that these problems are in no way limited to the US or the public sector. All Western countries have these problems to different degrees and it also exists within private enterprise which do not face the same problems outlined here.

Boeing e.g. had been terrible at making pretty much anything from planes to space rockets. Everything is delayed.

I suspect there are deeper more fundamental problems. E.g. how companies are managed and organized. Companies used to be far more engineering oriented. Today they are very sales and MBA oriented. There is also way more outsourcing and fragmentation of business. Business used to be far more integrated.
