I think that this is a pretty important conversation, as converting workers really is way too large a part of this game. And it's a pretty mindless activity; this would be a much better game were the majority of the decision making left to strategic decisions.
Even worse, after many many months of converting workers, it still isn't really clear to me how workers really shift from level to level. Most mysterious to me are low level workers, who seem to, rather than attend my surplus of schools, want only to be sucked up by the army; why is there no effective way to make us of excess LLW's besides through military means?
This confusion is symptomatic of an even larger problem; the vacuum where strategic decisions ought to be made on the part of the player is filled by the predispositions or ideological biases (call it what you like) of the game designers:
1. Private enterprise always trumps public enterprise in terms of efficiency, productivity, and overall social benefit. There is little room for the player to explore this question. From the perspective of a President, basically all the incentives are on the side of private enterprise.
2. There are some segments of a given society suited for little else than military service; no amount of investment (in health, education, and social security, etc.) can raise this segment's stake in the growth and profit of the overall society. The hierarchy and distribution of workers is totally based on the assumption that the largest segment of the population (LLW, housewives, disabled, etc.) must be subordinated to a much smaller but more educated/trained population. There's no way around this assumption.
I think that there's even more substance to this argument if one confronts aspects of the game that are relatively undeveloped or completely absent (conquest, diplomacy, government type, civil unrest, etc.). These are also perhaps areas that, if expanded or, in the case of government type / unrest, created, could provide a counterbalance to the strategic vacuum described above.
This game is getting boring. More strategy!
