A common point of disagreement in political discussions is about human nature. Some people say that men should make their own choices, and control their own money. And believe that only good will come of freedom. Others would retort that the rich will have more choices, and abuse them to gain more power. Or at least assert that some people will be left behind without help through sheer bad luck (or not having a level playing field). And that generosity is not natural, so the government must step in to help.
Roughly, right wing people take the first view, and favour free markets, small government, and people deciding for themselves how charitable to be. And, roughly, left wing people don't trust humans to be charitable or fair without being controlled by government.
So when a right winger says he isn't against helping people, he just wants to decide how best to do it, and make sure his charity is effective (the government, he will say, is wasteful and spends charity money badly), a left winger will likely scoff. The left winger will think this is just a trick to get out of giving any charity at all. Because the left winger trusts his government to do everything right, he will see any attempt to pay less taxes or avoid forced charity as, clearly, a selfish attempt to get out of paying one's fair share or to get out of helping other people.
So, who's right?
Well, I've got a way to find out. Despite high tax levels (paid by both left and right wing), it is commonplace to give additional money, by choice, to charities. Now, if the left is correct, we should observe that the greedy right wingers donate very little to charity. But if the right is telling the truth that they are happy to give money to charity, as long as they pick which charity, and give money in ways they feel are effective, then we will observe, despite taxes, that right wingers do choose to donate significant amounts of money to charity.
The following table ranks each state by how generous it is. This was determined by taking into account the amount of money donated to charitable organisations, and also how rich the people in that state are. In other words, one gets a high ranking by giving a large portion of what he has. The states are color-coded. Red states voted for Bush in the 2000 election (they're, to decent precision, right wing). Blue states voted for Gore. I believe the table speaks for itself. (Thanks to The Rantblogger for the table.)
