The question was answered. That you want to dismiss the moral question when that is exactly what you yourself are talking about proves that you have no intention of discussing the matter honestly. If you simply want to parrot rhetoric, find someone else to with whom to waste the time.
Responsible or not is kind of a moral question.
Should Citizen A feel some responsibility for his fellow man? That's a question only he can answer.
The role of government is to clean up the streets or not, depending on what percentage of Citizen A's feel a sense of responsibility versus those who don't.
It doesn't matter if Citizen A feels or even IS responsible - what matters is what the voters mandate. My humble opinion? If the vote is 50 / 50 for / against responsibility on a national level like it is now, kick it back to the states to keep their own streets clean.
They should...but that responsibility should NOT be coerced by Government against their will. It's an individual choice.
So, can I deduct 60% from the check I write to The People of The USA c/o I.R.S. this year because I don't feel like contributing to the military budget?
