Many "limited government" or "low tax" proponents are calling for more efficiency in governments. Unfortunately, efficiency is not a poor metric for any job.
Consider that even with long lines at the post office, the clerks, at least in Minnesota, ask, "Anything else?" The "efficiency" proponents would demand quicker processing of each customer, but the effective clerks give better service to each customer and may sell more stamps and other things.
The "efficiency" proponents would probably buy a heating system that gave the lowest cost per Btu. However, that heating system may not put out enough Btus to effectively heat the building. And if that low cost heating system was in an office building, the office workers may be so uncomfortable that they are neither efficient nor effective.
