Well Mormegil kind of answered your question and Arthedain73 did his customary ‘stroke my ego while only peripherally maintaining contact with the issue at hand’, so I’ll give it a try 
>> “just a question for the masses. Are most nations close to being self sufficient by turn 10?”
In my experience (not vast, admittedly) it varies from game to game and game type to game type: in FFA games individual players are more concerned about their economes and spend more of their resources on improvements but get less assistance from teammates, while in team games some economies are intentionally neglected to some degree in order to take advantage of nation abilites (CL agents, Hire for free nations, etc)… Also, 1650 games come to violence much quicker than 2950 games, meaning nations generally have less time to improve themselves economically.
>> “I am sure on a team you have one or two nations needing gold every turn, but most should be able to support themselves.”
Darks have pretty crappy economies in comparison to the Freeps, so it’s not really uncommon to see 2 transfers a turn (on average, since season changes, combat, etc can make it vary from 0 to 5 easily).
>> “Or in every game you have nations that need gold close to every turn? isn’t that difficult on the rest of the team.”
In a team game, it’s not really a problem since from an entire team point of view, 12 (or 10 or whatever) nations are economically supporting the armies/characters/fortifications of 12 nations… the fact that some nations pay more and some spend more isn’t always relevant.
>> “Do most people save at least one emis to improve their nations tax base?”
I’d shoot (with the largest caliber handgun I could find, at point blank range, directly into the neck) the player who didn’t have a home improvement emissary up until at least late game.
>> “touchy subject isnt it?”
Often
…some people don’t see a team as a team; contributing freely towards the common goal. Some see it as individuals cooperating together with scorecards to maitain an even balance, despite what evening balances at inappropriate times can do to the team.
