From the Critique of the Gotha Programme:

That the workers desire to establish the conditions for co-operative production on a social scale, and first of all on a national scale, in their own country, only means that they are working to revolutionize the present conditions of production, and it has nothing in common with the foundation of co-operative societies with state aid. But as far as the present co-operative societies are concerned, they are of value only insofar as they are the independent creations of the workers and not protégés either of the governments or of the bourgeois.
