Mistakes in themselves are unavoidable.

Furthermore, there is absolutely no contradiction between the separate organizations of revolutionary vanguard militants and their participation in the mass organizations of the working class.

Workers do not strike every day, they cannot do that the way they function in the capitalist economy. The way they have to live by selling their labor power makes that impossible.

And you cannot have a socialist revolution commandeered from the top, ordered around by some omniscient leader or group of leaders.

There is a process of social and of political differentiation going on in the real working class all the time.

If the workers do not fight for higher wages, if they do not fight for a shorter workday, if they do not fight for, let us say it in a provocative way, day-to-day economic issues, they become demoralized slaves.
