What is debt?

Here's one way to calculate it (htp: Burning Our Money): GDP less debt owed to foreigners, per capita.

But there's also total debts (foreign and domestic) compared to GDP, in which case the US owes 4 times what it earns, and goodness knows exactly what the equivalent is here in the UK.

And then there's future liabilities - pensions and healthcare costs that have effectively been promised, and will have to be paid for decades to come. The US Comptroller General, David Walker, has been touring the US for two years like Cassandra of Troy, trying to alert the public about this. His latest reported estimate is that these promises are equivalent to a lump sum debt of $53 trillion, and rising annually by $2 - $3 trillion.

It's an unholy mess, on a scale so large that even approximate calculations seem almost irrelevant. However, I strongly suspect that it is a misrepresentation to say that the problem is principally American. If only the truth were made plain - but those in the best position to say, have the greatest incentive to remain silent, or to mislead us.

The silent watchdog

Yet another important post from that heroic toiler (an oxymoron for classical Greeks), "Tyler". He looks at the economic implications of our ageing population and demonstrates that public expenditure cannot continue as projected.

The long-serving Comptroller Generals, both in the USA and here the UK, have recently retired. The difference between them is that the American, David Walker, has spent two years on an increasingly well-publicised Cassandra mission to warn the public of future dire financial dislocation, because of unfunded liabilities such as medical care and pensions. I may be doing a disservice to Sir John Bourn, but I can't remember any media fuss about him going on such a tour here.

Looking at the website for the National Audit Office, I see that in the FAQs, the spelling of "comptroller" comes second, after a dry summary of the NAO's role. However, the "find" option on my Windows toolbar can find no occurrence of the following words in that web page:

disaster
bankruptcy
poverty
IMF
inflation

Some barking from its kennel would now be most welcome.

The answer to Olduvai?

I am most grateful for a comment by "APL" on the heroic "Burning Our Money" blog, which directs us to an article on the potential of radiation-free fusion energy.

There is an international project (ITER) in the south of France to develop this, and if it works...

UPDATE

Thanks to GMG for a link to this discussion of fusion power, which tends to the conclusion that a successful and economically viable fusion system is a very long way off, if feasible at all, and we'd do better to concentrate on fission, i.e. the present type of nuclear power station.
