For example, if you have a +50 econ bonus from federalism and custom traits, does that mean that all of your population produce 50% more taxes?
Or does it mean that your income from taxes is increased by 50%?
What are the formulas that manage these things? How much money does 1 billion pop produce with say a 49% tax rate? How does bonuses effect that?
Also, if you have lots of "global" econ bonuses like for example Federalism, Federation Star Government, and custom racial traits, does that mean that you should boost your pop instead of building marketplaces? If these global econ bonuses are large enough, then isn't it better economically to raise population instead of building marketplaces?
