Long time IC worker, have said for years the same things. When the wall came down NSA and CIA at least should have closed up shop, laid everyone off, and restructured. They are still the exact same organizations with all kinds of appendages tacked on to try to make them work; and they fail.
Furthermore government in general is designed to expand. Nothing ever goes away. It changes its name occasionally but always hies more people. 3 years is tenure and one CANNOT be fired under almost any circumstances. If you have 20 really crappy workers and the job isn't getting done, its easier to hire 20 more than fire even one.
