The Market metaphor is a useful metaphor in understanding how the world works, and even anti-market (or those who are suspicious of "the market" -- practically everybody that I know) find it useful to rail against "it." However, I have decided that the market metaphor has a major flaw, both misunderstood by capitalists, anti-capitalists, and the "rest" -- the vast majority of ignorant and confused populi.
The problem with the "market" metaphor is that it limited in its focus on "economic" transactions. What is missing in the "market bazaar" model (simplification and abstraction) is the implicit "politics" that undergrid that market in context.
Context.
Now that the United States is more socialistic and probably implicitly as fascistic as mainland China, so the market metaphor argument (capitalism) gets confused.
What needs to be added to the market metaphor is what might be called the "political market." Marx essentially emphasized the political market where Rand emphasized the economic market -- neither was totally correct. The US and China are not considered as markets by either Marx or Rand. Moreover, businesses and organizations (NGO's, unions, associations, governments) are not seen as markets.
If one regards businesses, governments, and human organizations as "markets" -- then we have a "free" global "market" -- governments and businesses, and other organizations are competing and cooperating: in other words -- evolution (or involution and envolution -- in my terms). Businesses and governments are like eucaryotic organisms, they live and die, and innovations (and mistakes) are incorporated into the new or old "organizations" as metaman and hypermetaman evolves.
