David Rolfe Graeber (/ˈɡreɪbər/; February 12, 1961 – September 2, 2020) was an American anthropologist and anarchist activist. His influential work in economic anthropology, particularly his books Debt: The First 5,000 Years (2011), Bullshit Jobs (2018), and The Dawn of Everything (2021), and his leading role in the Occupy movement, earned him recognition as one of the foremost anthropologists and left-wing thinkers of his time.
The syndicalist answer is to get the whole working class into unions. Those unions take over their companies and become worker-owned co-operatives. They preference working directly with other companies doing the same. At some point, this reaches critical mass. The state then becomes unnecessary because the co-operatives handle everything between themselves.
Don’t forget, too, that a lot of “work” being done in a modern office takes, perhaps, 10 hours a week. People aren’t doing real work for 40 hours. That suggests that a company can be just as successful as any other while substantially reducing hours.
