2. Be angry that government is inefficient.
3. Goto step 1.
Have you been to (the equivalent of) DMV in other countries?
So let's say that the government produces one driver's license per $100, and I'm angry that it costs that much. Your proposal is that I will be happy if I instead spend $120 per license?
In that case the GP would be talking about appropriating more money for more DMV employees so that people could be done with their business their more expeditiously.
In your case, you're talking about monetary efficiency which is a different thing and might be better served by less employees serving the people.
And I guess it's up to society to decide where that line should be drawn in terms of both monetary efficiency for the tax payer and temporal efficiency for the person waiting in line.
1. Recognize "government is inefficient"
2. Use as an excuse to give the inefficient more with which to be inefficient
3. Goto step 1
Recognizing people are bad at some things doesn't mean it's a money problem nor does it mean that comparing different environments is apt.
2. Remove a stick of RAM from your computer to teach it a lesson
3. Get mad that your computer didn't magically do more with less
Far too often the solution is to continue removing RAM in the hopes that the inefficient process magically fixes itself. It rarely does.
There are certainly ways they could make the DMV more efficient, but don't mistake the almost universal unpleasantness of DMVs for inefficiency.
