However...
Whenever I get to the end of an explanation of economic activity like this (and for the record, I like, and find Tim's most useful) I hear a "Ta da!" in my head as if I've been watching a magic trick.
Clever, complex, utterly convincing and yet I know there wasn't a rabbit in the hat, dove in the wine bottle etc.
But this trick changes lives.
Endnote: I'd love a Tim article on privatisation. Has it worked. And for whom?
