Of course, while you're thinking about the things your taxes provide, remember that it's your taxes, not the taxes of America's most profitable company, because that company doesn't pay taxes on billions of its profits. (Meanwhile my small company which ekes its way into the black, pays its taxes and lays off three people.)
Of course, large corporations also benefit from roads, fire companies, the FAA and schools, and they've got the same speech rights as actual people, but making them actually pay taxes the same as other "people" is a step too far.
(With a tip-o-the-hat to Blue Virginia.)
And then there's this bit-o-zen.
