True, but you have to keep an eye on the systems, too. Overburdening systems can bring about The Fall of Rome. I guess that's your #5 in a way, but
those systems are things like capitalism, socialism, social programs, etc. Even the laws themselves (and justice) form a system. Gotta maintain the pressure release valve or the boiler blows.
Maintenance costs (debt) can blow it, but so can pressure (peasants with pitchforks). Should we take fuel to service that debt from the big ol' gas tank or try to summon it from more locations but in smaller quantities? Basically that sort of thing. We can adjust as we go along, but you've gotta know which way to adjust in the present. Should probably include some sensors in there that tell you something about that (and it does, but people don't always check them before having opinions).
