Classical laborists and mutualists were anti-capitalists. Some of whom predated Marx.
As I said, a mutualist economy or economic democracy has never existed. The modern arguments for economic democracy were first published in a book released in the 1990s. However, we have plenty of examples of worker coops and employee-owned corporations working well under capitalism. An economic democracy or mutualism differs from capitalism in that all firms are mandated to be worker coops
