A pretty well-made programme which made some good points, but to be honest, some of its basic premises were little more than journalistic shock tactics.
For starters, it's ground stone was that the UK national debt is 4.8 trillion pounds. Well, er, no it isn't! In fact it's not even close. The real figure is a matter of debate. If you believe the official figure (which is massaged to make it seem as small as possible) then it's about 650 billion. If you believe even harsh critics, it could be as much as 1.2 trillion (which includes underwritings and liabailities that are impossible to estimate accurately without a chrystal ball) Even the most dogmatic, sensationalist worst case scenario panic merchants would put the figure well below 2 trillion. In short, they've inflated the figure by anything between 250 and 800 percent for shock value.
All of these figures are, of course, too high (I think everyone can agree!), but the only way you could come up with the 4.8 trillion figure is to include all projected pension payments for everyone still alive. Nobody ever does this when calculating national debt. It's like saying that because you buy a bottle of wine every week (price 5 quid) and intend doing so every week for the next 50 years, that you're already 12,500 quid in debt, despite the fact that you haven't actually spent any of that money. It's also a bit rich (if you'll pardon the pun) given that they then claim that these pensions are being 'stolen' from future generations. Think about that. It doesn't really make sense (well, regarding the pensions anyway!)
Then there's a bit of scare mongering about 'What if the UK economy went the way of Greece?' Well, fair question, but is it really relevant? The UK currently has an AAA credit rating. The best in the world.
They were spot on about politicians over-promising on spending to get elected (in my opinion anyway) but then they got in a load of politician who were guilty of exactly that to back up their argument. (If you don't believe me, just look at what happened to the national debt throughout the Thatcher, Major and Blair years.) Hardly convincing stuff!
