Any producer working in concert with other producers that produces more or better outputs and or with less cost in resources etc
Then if producing in isolation
Can be paid their independent value maybe more
and still leave a surplus of value
Over time production in co operation can lead to specializations that make independent production by the specialist essentially skill less common labor capacity
They are trapped into exploitation
Co operatives as a social counter follow easily from this fact see Owen
But like an organ trans plant co ops rarely thrive inside a capitalistic surrounding system
But by itself co ops hardly challenge the capitalist system anymore then trade unions
Challenge the capitalist system
In fact seems most mcjobblers enjoy the high take home and conditions control
achieved by collective bargaining at least as much as co ownership rights
The question becomes
Are profit seeking outfits more dynamic and innovative and Cost cutting then co ops
Maybe
No analytic answer to this question eh ?
