The advantage of the market system is the market yields efficient allocation of resources.
As everyone knows the CME is dominated by one or two big players. As can be seen by the above graph, the NASS survey and the CME are the same, except for a time lag.
The Bureau of Labor Statistics (BLS) publishes numerous data bases including the Producer Price Index (PPI). There is a PPI data base for "natural cheese." The correlation between the CME block Cheddar and the PPI is .95 - pretty close to a perfect correlation.
Now if you believe in a market system, you have to raise all kinds of doubts about the control exerted by so few players.
Maybe what we have is "Plutocracy is rule by the wealthy, or power provided by wealth." http://www.google.com/url?sa=t&source=web&cd=1&ved=0CBkQFjAA&url=http%3A%2F%2Fen.wikipedia.org%2Fwiki%2FPlutocracy&ei=4osRTJaJFMTflgfRh7iaCA&usg=AFQjCNEO9XicOAj2rmPhTB0jNPmq_i44tQ&sig2=ERR6DpVgaormpiXQCbvJ5A
Not a pleasant thought.
