Lenin makes a good point about this in What Is To Be Done?

We have said that there could not have been Social-Democratic consciousness among the workers. It would have to be brought to them from without. The history of all countries shows that the working class, exclusively by its own effort, is able to develop only trade union consciousness, i.e., the conviction that it is necessary to combine in unions, fight the employers, and strive to compel the government to pass necessary labour legislation, etc.

The theory of socialism, however, grew out of the philosophic, historical, and economic theories elaborated by educated representatives of the propertied classes, by intellectuals. By their social status the founders of modern scientific socialism, Marx and Engels, themselves belonged to the bourgeois intelligentsia.

In the very same way, in Russia, the theoretical doctrine of Social-Democracy arose altogether independently of the spontaneous growth of the working-class movement; it arose as a natural and inevitable outcome of the development of thought among the revolutionary socialist intelligentsia. In the period under discussion, the middle nineties, this doctrine not only represented the completely formulated programme of the Emancipation of Labour group, but had already won over to its side the majority of the revolutionary youth in Russia.
