I'm sorry it took me so long to reply, and more so because of what I have to say ..
I'm not a fan of management sims, so if you ask me what the point is, I'll say there is none. They're a simulation (more akin to toys than games) of bean-counting (as much fun as a stick in the eye). A fan would probably tell you that the point is to make the little people do your bidding (maybe not in those words). Essentially, the aim of the game is to "build a thriving nation", which, to me, means that there is no clearly defined goal, or it is too subjective to be definable, and that's the first thing I'd want to set straight, although, come to think of it, I vaguely recall elections which you had to win to keep playing, or something like that. Honestly, my experiences with these "games" have been that unmemorable.
On a more constructive note, looking objectively at your own experience of this type of game in the wider context of game design, have you found the play experience, and in particular its conclusion, satisfying? And if so, what did it satisfy? I think that that will give you your answer.
