Billyjoeallen has the point go right over his head. Shocker.
My question is a test to see who cares about their ideals and who is just greedy. Judging by your response, it's all about the money for you, which suggests to me your odds of willfully giving anything to charity are extremely low. If that is the case, why should I believe your ridiculous "support through voluntary charity" argument. You clearly don't.
Your question is flawed because it substitutes involuntary action with involuntary action. A question such as "how much do you think you would contribute to charity if you were untaxed" would perhaps be more illuminating (though useless for totally different reasons)
