Tax Fun!

Had the game for a few weeks now, I dig it. But I did notice, there isn’t that much fine control over taxation, esp income tax. It would be interesting if you could rejig a tax system so it will recieve the same amount of income but shift the taxation burden to a different income group or try experimental stuff like flat taxes, or even just leaving the tax rates the same but giving tax deductions to certain groups (although I guess this is already modeled in some instances, such as agriculture subsidies and child benefits)

Does anyone else have any tax policy ideas?

I’d certainly like to see tax deductions more. Also, how about the income tax starting threshold?
