I googled Peter Singer -- see, e.g. here. He's a hard-line utilitarian, who believes that defective newborn babies should be killed, and that meat-eating is wrong. Is his argument for taxes that the government will use our money more wisely than we will?
[Raak] Sorry, I haven't looked it up yet and I can't remember all the details of the argument off the top of my head. I'll try and find it and post it for critical review here, as I found it pretty persuasive I must admit. (BTW, aren't you a hardline utilitarian too? The Rover argument hints that you are.)
Mm. On second thought, maybe it doesn't. I think the gist of the Singer argument on tax is that we all subsist within superstructures of wealth, and that "your" money wouldn't buy you anything without those superstructures, and those superstructures have costs that you don't generally pay directly, but you can, sort of, in a way, if you will, pay them indirectly via tax. But as I say, I don't remember the detail and may have that wrong.
[Projoy] I've always thought of Raak as more of a libertarian. But I would be interested to know how he describes himself. As for "whose money is it anyway", variants of that kind of argument certainly predate Singer. Broadly speaking I take the view that our ability to transact is only secured by governments that protect property rights, enforce contracts, jail muggers (unless they are managing large corporations, of course), that kind of thing. The social contract that we agree to is that, in return for these guarantees, we accept that governments have the right to tax us. And once that right is established, there are then good public policy arguments for various kinds of taxing and spending by government. That's pretty loosely articulated, but then it is very late here in Singapore. :-)
