OK, my apologies - didn't mean to tell you something you already know. If you know all this though, I don't understand why you would say "we should just keep it very simple", if you accept it isn't... unless you want to knowingly ignore the effects of what you're proposing?
> I remember reading an article once by vince cable, who was horrified at the debt and interest payments for uk as it curtailed the ability of any govt to do things.

Yes, it would, by the amount said above. But the option to magically get rid of existing debt isn't there; so it's a bit of a straw man argument to say that. The question is not "wouldn't we prefer not to have any debt", but "does taking on more borrowing now hurt or help us on balance".
> We always of course must remember that economists have different views.
Up to a point that's true, but I think the points I make above are considered mainstream.
