Magic money tree?

I'm sure I've been down this road before - the Government has no money!!  The government controls a certain amount of money, but this is either money which it has taken from us - you and me  - through taxation or other revenue raising methods, or money which it has borrowed, and will eventually have to be repaid (by us!).    So....? Well, when we discuss whether and on what the Government should spend money, let's keep to the forefront of our minds that this is our money we're talking about, and if it involves extra money, then it's us who will have to find it.  By the way, I use Government (capital G) to refer to the current administration, and government (small g) to refer to the concept generally.
