Nice article by Jonathan Schlefer.
… no one ever showed that some invisible hand would actually move markets toward that level [equilibrium]. It is just a situation that might balance supply and demand if by happenstance it occurred.
To quote myself in the comment section (even though it’s bad form):
Would the “invisible hand of the free market” work in a perfect market with 100% transparency?
It’s hard to say without being able to observe in the real world; however, I would say the answer is “yes”
Is a perfect market attainable? Absolutely not.
What if government stepped out of the picture, wouldn’t that help? Nope. People are people — People are imperfect.
I know those who — in order to get around this problem — like to believe that a person’s individual imperfections are unimportant, and that the ideal market state will be reached. To them it isn’t important that people make the “correct” decisions but only the decisions that are correct to them. For instance, some people prefer to buy lesser quality things for less money even if it costs them more in the long term to replace items more frequently. I would say that a trend like this is created by a marketer’s ability to control perception and to obscure the facts about the true value of items. In the mind of a true believer, this is simply personal subjective truth, and if that’s the way the market moves, it’s because people “want it” and it’s the “right” way.
I can almost accept that argument, but let’s take it to the extreme to see if it really holds up. What happens when a human being is addicted to drugs? Very few would argue that they are rational at this point. However, it is human nature to become addicted to drugs or many other (less or more harmful) activities. It is human nature to be irrational. In a truly free market, there is no problem with drug sales increasing because demand increases. Assuming that human imperfections are just subjective choices and are logical as far as the economic model is concerned; therefore, a state of drugged happiness for most of the population, while an elite group controls all wealth is a possible outcome of a perfect market. I can not accept this. If you make an exception to the free market to control the sale of heroin, there is no justifiable reason to stop at this and you must control usury and misleading advertising as well, which we have historically been very week in doing. Even if you only leave it at these three things (while I would argue for more controls) you have already admitted that a market is controlled by people and not by an invisible hand.
Simply put, a perfect market is an impossibility, so the idea of an invisible hand that works only when an impossible scenario is met is just ridiculous. The hand is not invisible. It is the hands of individuals — yes, some government — but more directly entrepreneurs, executives, and board members who make decisions to influence demand by changing perceptions and creating new market imbalances. This leads of course to wealth extraction — or creation if you believe in unlimited growth — but either way it is not the equilibrium which the “invisible hand” is supposedly moving towards.
