here is something i thought funny
80% tax = 100% aproval (this is with all my + moral modifiers and what not) the tax on each planet was giving -126%
81% tax = 1% aproval (thats not a typo its 1%, the - modifier was at 321%, the - modifer at 82 was at 340% )
so its not just exponetial growth, but there is a spike.
