I try to post regularly on what the defense department spends per day. It's very illuminating to realize that one day it might spend $40 million just on fanny packs or fruit for the cafeterias... never mind the billions and trillions it's spending on weaponry. The same 20 companies show up over and over on these contract lists... Raytheon, Boeing, Northrop Grumman, SAIC, etc., and their venn diagrams show why: they employ many former DoD personnel.
Revolving door politics indeed.
