But we must take account of the numbers. As Orwell might put it, 'some tax, good, more tax - double plus good'. Not exactly true is it? On the whole, (and this is not a zero tax argument) the following from Milton Friedman seems a truism to me.

“When a man spends his own money to buy something for himself, he is very careful about how much he spends and how he spends it.When a man spends his own money to buy something for someone else,he is still very careful about how much he spends, but somewhat less what he spends it on. When a man spends someone else's money to buy something for himself, he is very careful about what he buys, but doesn't care at all how much he spends. And when a man spends someone else's money on someone else, he doesn't care how much he spends or what he spends it on. And that's government for you.”
