Although the term "capitalism" has long worked as a shorthand signifier for a market economy, there is a sense in which to use it at all is to accept the socialist's premise that a market economy is a consciously created system, manipulated by its creators for their own material ends.

[A] modern market economy is an immeasurably confusing and constantly changing combination of associations and exchanges-not a "system" of any kind.
