Those who foment “worker revolutions” obviously plan to lead these uprisings, just not from the front. They don’t actually care about workers at all. To them workers are useful idiots who need them to take the lead and “liberate” them from their employers. They see workers as a tool by which they can gain control of society and rule the world through them, or as a patsy if they fail in their objectives. They do not, never did, and never will intend to actually put the workers directly in charge of the means of production.
