Is it possible this limit is intended to simulate inflation caused by having a substantial treasury?
I've been told it's technically "graft".
This used to be specified in the Wiki Tax Article
. This is the malus referred to in the following equation. At one time I thought a value of 10% was mentioned but at high levels of income (> 1 million bc/week) this seems closer to 20%.
34.5 * sqrt(population_in_billions) * tax_rate * (1 + (sum from buildings on planet)) * (1 + (sum from racial bonuses/maluses) )
See reply #5 from frogboy for the definitive word on this in the following thread
. Also note the date.
Thanks for this explanation as to the rationale behind the use of 'graft.'
Some ideas for future patches/expansion packs:
(1) As has already been stated, I would like to see this scaled to the map size one is playing on, if possible.
(2) Another idea, as may have already been mentioned, is to scale the level of graft to ones moral/ethical and political allignments. The 20% graft penalty, across the board, regardless of one's ethical and/or polical allignment or level of government seems rather arbitrary to me.
(3) Again, as already been mentioned, giving the player the ability to toggle this on/off in the options screen.
My two cents as a newbie, take them for what they are worth
