Is math subjective?

First reaction: of course not! But I get pretty confused when thinking about politics, and then it almost starts to seem like it is.
One thing that I've learned up from spending too much time on the internet is that people really like to complain about money. The rich complain that they pay all the taxes. The poor complain that the rich have all the money. If both claims are true, what are we arguing about again? Of course the tax line with which we force income re-distribution is going to be perceived as unfair if you're on the wrong end of it, just like it's much easier to agree with Robin Hood if you're not the one being stolen from. Shouldn't there be some line that everyone can agree on?
In my ideal mathematical world, there exists a solution to the system of equations describing how government should be paid for, what it would span, and who it covered. But this world is far from ideal, and no one can say what is Fair. Arguing politics seems pretty useless to me because people simply feel differently, and there is no right answer in feelings, unlike in math. Even considering the salaries politicians get, I'm extremely glad I don't have to do it for a living.
