I don't like the Salvation Army specifically, but I do take your point, and I do give to charity.
You can't honestly believe this can you? I mean, I can understand the argument that using government to cure social ills is less efficient and effective than private charity (I disagree but I understand it), but you can't honestly believe that government has never done any good at all, can you?
It's not that I specifically desire to pay higher taxes, it's that I would be willing to do so in order to support better social programs. But the state of federal spending is such that I disagree with its priorities, and so I'm not just going to give them more money that they'll spend on something other than what I want them to. (To be clear: I pay my taxes, I'm not one of those crazy people who refuses to because they don't like what the government spends it on, I'm just not going to voluntarily give more.)
Basically the crux of it is that I wish the government would do more to help people, and I would be willing to pay more in taxes in order to accomplish that. I don't have some desire to just give money to the government for the sake of giving money to the government.
This I agree with 100%. ^5
