"Adam Smith believed in "an invisible hand", ie, the marketplace, that has the ability to regain sanity after a period of insanity, through the force of the combined participation of each and every participant (whether it be consumer / banker / manufacturer / miner / farmer)."
NO, No. no no.
Read his works. Oh, you will also nee to read Mandeville because that is what Smith is replying to. "Private Vices ... may be turned into Public Benefits"
or at LEAST read the wikipedia page.
Plus, the invisible hand idea has been shot down, completely. IT doesn't work anyplace except in an abstract version of the world that only exists in the minds of moral philosophers.
He uses that same term to describe the orbit of Jupiter, as well. And since his note where destroyed at his(Smith's) request, for all we know he was referring to god controlling markets. granted, that's not likely, but the point remains.
