I know David Cameron has raised this subject today but I'm not trying to start a party political debate.
I just genuinely don't understand the theory behind the strategy. I can get my head around the fact that a country, which doesn't have a large national debt, can let some of those "spare" funds filter down to stimulate economic activity and bank lending.
But how is it supposed to work when the UK has a huge national debt?
I don't get it. Is it spending against future growth? Surely that cannot be a sound way to proceed?
I confess to having a very poor knowledge of economics - am I missing something here? Can someone please explain it to me in terms I will understand?
