MSOCS,
A truism doesn't stop being a truism just because you don't like it.
The argument was made by PFMG that a government that was spending more than it was earning shouldn't reduce the number of public servants, as they pay their full tax contribution. This argument is simply incorrect, as self evidently the government pays public servants more in salary than it gets back from them in taxes - thus public servants are a net drain on the government purse.
If you bothered to read all 4 lines of my post, you will see that I also used the phrase in most cases a necessary one when referring to the costs of employing public servants - and I include the armed forces in this category.
If you don't like the message rather than counter it with a logical argument you attack the messenger - very enlightened - and very reminiscent of the tactics employed by a certain political party - but then I suppose this is pprune after all so I shouldn't expect any better!
