If you're in the US, you probably pay a much lower percentage than you do in many other nations. That much I can establish.

Wikipedia has some good tables but, like you suggest, compiling that data is not that easy due to biases. There are also different names for the taxes, different categories, differences in reporting, etc... About all I can conclude is that I don't pay much, compared to what I'd pay elsewhere, in taxes.

I actually don't mind paying taxes. I do mind how the money is spent, but that veers into a digression and politics. So, I'll skip that for today.
