There is much reference in every conservative agenda to "small government". The fact of life is this: If you need a service, someone will have to pay for it.
The question is thereby not about "small government".
If the agreed upon needed service is to move 6 tons of whatever from a A to B, someone has to pay to move 6 tons from A to B. The kilowatts to do that are a physical constant.
There is NO inherent reason why a government could not move the 6 tons from A to B at the same price, or even cheaper, than a non-government organization. Bad public management? – ask Enron.
Unlike a commercial company, a government does not have to make a profit margin. It does not have have to pay a "rent". It can thereby calculate and deliver a service at a lower price than any commercial enterprise.
The whole "privatization" stuff is thereby just a way to enrich the well connected (and bribing) folks who already "have". It is never about the people who need.
When will this be understood?
