Companies that sell shonky products under false pretenses are typically prosecuted by the authorities. Those that sell shonky products generally are typically run out of business. But there is one class of such products that seem to escape the scrutiny of both the authorities and the market. Indeed, they seem to have bluffed many governments into believing that shonky is good. Last week, the patently irrelevant Moody’s rating agency downgraded Britain’s sovereign debt ratings from Aaa to Aa1. The fact it was headline news indicates how stupid we all are. The fact that George Osborne then had to lie about what it meant showed how stupid he is. The fact that the Opposition leader described it as a humiliating blow showed how stupid (and opportunistic) he is. How a company that was complicit in the financial crisis can command so much free advertising is beyond me. I must be stupid! The fact is that the latest ratings are without meaning or import.
