5. Speculators and middlemen are yet another species of parasites. In a theoretically totally efficient marketplace - there would have been no niche for them. They both thrive on information failures. The first kind engages in arbitrage (differences in pricing in two markets of an identical good - the result of inefficient dissemination of information) and in gambling. These are important and blessed functions in an imperfect world because they make it more perfect. The speculative activity equates prices and, therefore, sends the right signals to market operators as to how and where to most efficiently allocate their resources. But this is the passive speculator. The "active" speculator is really a market rigger. He corners the market by the dubious virtue of his reputation and size. He influences the market (even creates it) rather than merely exploit its imperfections. Soros and Buffet have such an influence though their effect is likely to be considered beneficial by unbiased observers. Middlemen are a different story because most of them belong to the active subcategory. This means that they, on purpose, generate market inconsistencies, inefficiencies and problems - only to solve them later at a cost extracted and paid to them, the perpetrators of the problem. Leaving ethical questions aside, this is a highly wasteful process. Middlemen use privileged information and access - whereas speculators use information of a more public nature. Speculators normally work within closely monitored, full disclosure, transparent markets. Middlemen thrive of disinformation, misinformation and lack of information. Middlemen monopolize their information - speculators share it, willingly or not. The more information becomes available to more users - the greater the deterioration in the resources consumed by brokers of information. The same process will likely apply to middlemen of goods and services. We are likely to witness the death of the car dealer, the classical retail outlet, the music records shop. For that matter, inventions like the internet is likely to short-circuit the whole distribution process in a matter of a few years. 6. The last type of market impeders is well known and is the only one to have been tackled - with varying degrees of success by governments and by legislators worldwide. These are the trade restricting arrangements: monopolies, cartels, trusts and other illegal organizations. Rivers of inks were spilled over forests of paper to explain the pernicious effects of these anti-competitive practices. The short and the long of it is that competition enhances and increases efficiency and that, therefore, anything that restricts competition, weakens and lessens efficiency.
