Dolphi, You say it's important to consider all measures, but then use only one to try and prove your point. The debt is also almost never referred to in absolute terms, but in a normalised term, since a few billion in debt would be a problem for a country like Iceland, but almost nothing for a country like the UK. When people talk about the national debt over time, they almost never use absolute figures unless they're trying to mislead by throwing large looking numbers around to boggle the mind. We don't compare today's debt level with the 1940s debt level in absolute terms because that would be absured. When talking about relative measures, whilst there is some variation, it isn't that large and changes in GDP do actually affect our ability to pay it back, or not. You repeatedly highlight on this forum that the UK almost never manages to raise more than 40% of GDP as tax. You never use absolute terms for that figure. That is because it would be absurd and become invalid pretty much the next year. We can't easily compare absolute terms, which is why we normalise to an adjusted figure or use something relative. TL;DR the absolute figure is almost never useful in a comparative discussion.
