look around...
We should be able to chose different options for national affairs, not only by chosing if we want communism, democracy etc. What about free market economy, command economy, taxes, opression of the people, free people? This should create more ways to make your country grow. For example, if you want to be communist, you should opresse the people and have command economy. So there would be many combinations to make and every would be more or less effective. Yet it recquires some economics knowledge from firaxis and patience from the community, but it would make out of CIV a more long termed game.
I got this idea after reading the article about slavery and free speach, which would have a bigger impact in your civ. Thus my suggestion should be programmeable by Firaxis.
