At last the BBC has found the real cause of the Crash, and the resultant travails in the world economy. It wasn't the bankers, and it wasn't the politicians. It was in fact the mathematicians.
I've always suspected the mathematicians. While the Chemists were slaving in the Dantean conditions of the Dyson-Perrins lab, and the future Prime Ministers were playing tennis or trashing restaurants, the mathematicians would simply not bother getting up till tea-time, slop around in cable-knit sweaters, then get drunk and set fire to themselves on electric bar-fires. They were clearly unable to accept responsibility, and would sit around until the early hours plotting, as it turned out, revolution.
We shouldn't underestimate the power of mathematicians. Jealous of the ability of Physicists to attract the oppostie sex; without the ambitious intensity of a PPE student; not being in a subject that had the potential for explosive catastrophe like Chemistry, or smirking at the fate of the Younger Despenser - what wry amusements did mathematicians enjoy?
Well, it turns out that all along they were planning the downfall of the economic system. As time went by, the complexity of trading systems were such that computers were used, rather than the gut-feel trading that we see in documentaries such as "Trading Places". The basic foodstuffs on which the whole world depends were made dependent upon futures options, derivatives, options on derivatives - the real world where farmers grow wheat, which people buy and make bread from, was submerged under increasing depths of ever more complex financial models. Yet the computers that crunched the numbers that underpinned the models had the ability to decide who had grain and who had not; who lived and who starved.
And everyone was forced, small and great, rich and poor, free and slave, to receive a mark on their right hand or on their forehead, so that no one could buy or sell unless they had the mark, which is the name of the beast or his number.
Oh... sorry, I seem to have gone all apocalyptic there. Now, I'm not saying that mathematicians were in the power of the Dark One. But it does seem to me that somehow, like a thousand geeky Sorceror's Apprentices, the mathematicians set upon the world something which the capitalists thought that they could use, but which they couldn't control. If computers are able to manage who owns the food supply, they are literally able to decide - in their blind, uncomprehending way - who lives and who dies.
It is an irony perhaps that a world that started through a Word could be brought to ruin by a Number. I don't really know what to do about it, though - unless perhaps we all get allotments?
