answer:For me there are a number of things, one thing at least, I don’t know if an 18th century economic model is capable of setting a standard for 21 century financial instruments, for example, the whole mortgage backed securities debacle. If the costs and benefits are hidden inside some inscrutable and incredibly complex financial instrument, where no one really knows exactly what they are getting themselves into, is that something where the rules of the market as described by Adam Smith apply? It is a matter of trust. Do you trust the market, do you think “the market” is actually capable of taking care of everything? Can the market really sort it all out for the best? Personally, I don’t think so.
