Well, if I cross the border on foot, I don't think I would be using the roads. Besides, roads are paid for with fuel taxes. So, I use a sidewalk now and then. Is that what someone who is at the poverty level in income, has to pay income taxes for? Using a sidewalk once in a while?
Is that what I paid income taxes for 44 years, for? So I can be taxed again when I can least afford it? Is that your idea of being fair?
What's next? The air we breath? I'm starting to peel back the onion here. I see what your aiming at. You want the tentacles of Big Brother to invade every little nook and cranny of our lives, then everybody is subject to the state. It infests society just like it has infested the minds of what would otherwise be ordinarily competent people. Did you get attacked by terrorists today? No? Well, you owe us for that. Did you die from dirty air or water? No? You owe us some money, honey.
So, if you use any of the public infrastructure, you better pay some income tax, no matter how little you make. If that is your argument, then you are destroying your whole political philosophy. The compassionate liberal attitude of yours is overwhelming.
