I have set up a form of Government that is a Social Democracy. Stats that I find are fairly useful are :
Social Democracy
Communal Corruption
Low War Protests (I forget the name)
Hurry Method : Purchase
Extra Unit Cost : 2
Free Units :
0
Town 2
City 4
Metro 5
Or, you could set War Weariness to Nil, as of course, all wars the Government Fights are Just!
I complement this with a 'Monument' wonder, which reminds all citizens of thier loyalty to the state and the countless sacrifices the people have made to attain this form of Government (Not to mention building the damn monument!!). It increases production by 100% and generates a 'Volunteer Worker' every 5 turns that works for free (No Upkeep costs) 150% worker rate. Of course, the monument is available only with this form of Government and COSTS a lot.
