as a natural monopoly- sure
The military tends to be a natural monopoly and as such is provided by gov't and
given a statutory monopoly.
Nevertheless, it does not mean all services are done efficiently
Remember $55,000 toilet seats?
That's a pretty old example.
How about one that's current.
The government expects contractors to provide full-time employment, health care, and several other requirements mandated by Congress in order to bid for contracts. Automatically this raises the costs of the contract. Now the Dems want another requirement. They want the bidding company to meet ecological requirements. They must meet some crazy standard, or Green-job standard, boosting the costs even more.
Who gives a damn that the job was even completed in a satisfactory manner. The contract calls for the equipment or building to be constructed or installed. It doesn't specifically call for it to actually work in a specific matter or even work at all. It just says that it must be done and what must be done. Construction only requires a one year warranty so usually by the time flaws or manufacturers defects are discovered in the work the warranty has already expired.
This is an example of current governmental waste.
Another example is when a building that should have been torn down is remodeled and shortly after the remodeling is complete the building is torn down and a new building put in it's place. The new building has inherent flaws that become serious maintenance problems in the future. HVAC systems are installed that cannot keep up with the heat load of the building or produces mold and mildew because of design flaws. The money is already gone by the time this is discovered. I see this happening on military installations all of the time. This all falls under the Defense Department. This is a lot of the waste you see in defense.
