I wasn't talking about just taxes.
Well, you should be. Along with the stuff taxes fund.
Taxes are the only thing relevant to you when you vote?
I know for a fact that taxes -- and the things they fund -- are the only relevant items consdiered by most politicians when they govern. Or rich donors of both parties. (There are a few folks on the fringe of both parties who act based on social issues or foreign policy, but ~90% of politicians and rich folks only care about taxes.) Since that's the case, I have to think about these issues first and foremost, yes. Other voters should also.
I tend to think about what taxes will fund. I would like to be taxed more and have better social services. Also, it's not fair that the rich get all the tax breaks. Why do I get full social security when I retire, but I stop being taxed for it after my income for the year goes above a certain level? That's a load of crap.
