It's funny, discussing this story on Facebook, a friend of mine, staunch left-winger, said that Thatcher "pissed the money away". Hang on a second, I said. Are you now saying that government spending/the welfare state is just pissing money away?
Having said that, I don't quite recall Thatcher being famous for spending oil revenues on expanding the welfare state (and it doesn't sound like something her supporters, then or now, would approve of) so maybe I'm missing something here?
