A consistent anarchist must oppose private ownership of the means of production, and the wage-slavery which is a component of this system, as incompatible with the principle that labor must be freely undertaken and under the control of the producer.
Noam ChomskyLanguage would have evolved first as an internal object, a kind of "language of thought" (LOT), with externalisation (hence communication) an ancillary process. I can't review here the strong and growing evidence to support this conclusion, but I have elsewhere. There are ample reasons why having a LOT would confer selectional advantage: the person so endowed could plan, interpret, reflect, etc., in ways denied to others.
