National Treasuries are not the same as the National Economy. I don't see gold as being the economy but the treasury and the portion of the economy that the state holds. Surely, Nations can save... they just tend not to. Part of the reason for this is because if they do they're sucking employment opportunity out of their own economy. By so doing, they're shooting themselves in the foot and causing their economy and thus income to shrink. Thus why I say that if you have all sliders at 0%, thus holding onto all income as much as possible or having the tax stream all go directly into your immediate obligations, you should be causing drastic inflation. Science does represent employment, and the statement that gold doesn't is a bit dependant on the angle from which you're looking at it. If you're on 0% sliders, it means you're budgeting nothing towards scientific efforts, culture or morale boosting efforts for society, and nothing for espionage employment and are just taking as much as you can... that does mean less employment you're investing in all in all, except that you're still spending money on maintaining state owned buildings (upkeep), military and state functions (civic upkeep). If you spend gold to hurry a build, however, that'd be an immediate economic stimulus guided by a program to get something done in a very short time. Thus in this way gold does mean employment, but you may be meaning gold from the slider perspective in that comment.
