Okay, but I don't regard you as an sort of moral actor for that: you intentionally don't do something you readily admit would make the situation better, out of your emotional needs, while politicking to force everyone to do the thing you're not actually willing to do yourself.
So no, I simply don't believe you: I don't think you believe you should pay higher taxes, I think you believe other people in your income bracket should, to run society the way you envision. If somehow that didn't apply to you, but applied to every one, well that would be just fine wouldn't it?
I originally didn't agree with GP, but the posts like yours trying to refute it are actually bringing me around to that position -- because they're deeply morally compromised, full of special pleading, and so on.
